Ask Slashdot: What Can You Do With Old Coaxial Cable?
Long-time Slashdot reader Theaetetus writes:
I recently bought a house and the previous owner left some coax (mostly RG59) running between rooms for cable distribution. I'm a cord cutter and don't need cable, and I've already run CAT6e everywhere. But before I pull the RG59 out and try to seal the various holes he left, I figured I'd pick Slashdot's brain: can anyone think of a good non-cable use for spare coax lines?
Leave your best answers in the comments. What can you do with old coaxial cable?

Makes a nice random wire antenna for shortwave
Unless they are unsightly why bother? Just leave them be. You never know when they might be of use again at some point in the future.
I've submitted a lot of posts to Slashdot in the past. None of them were published. And now the publish this question.
I'm really disappointed...
How about, don't pull it out or tie some other wire that can be used to pull something new through to it and leave that in the walls (like one electrical wire, in Europe electricians often use black for that). That way if in 10 years from now you want to replace it with whatever is cool then you simply can pull that through.

I don't know why you'd bother removing the cable. If you don't want the jacks remove them and cover the holes. Make the spot in someway where the cable is though so you can find it again.
Stripping the cable out of the wall for no reason would be a bad idea imho. You never know it could be useful again for something. If nothing else should you ever decide to move the next person might not be a cord cutter and might be really glad to have those cable runs.
Repeal the 17th Amendment TODAY! Also Please Read http://www.gnu.org/philosophy/right-to-read.html
Most folks that we help with cutting the cord (we are a regional WISP) end up setting up a local off-air antenna to catch news and local programming.
With a cable already run to the Ham shack. Amateur Radio FTW!
If its in the walls our out of sight just leave it. Its a communication cable, which means it was designed for a specific purchase. To carry signals and prevent outside interference. In the older days you could have used RF out on devices to setup a network of TV's or even a older security camera setup. If anything look around for a older close circuit camera setup which many used BNC distribution connections, but you can easily buy adaptors.
Recycle it!
Anons need not reply. Questions end with a question mark.

I mean really! Why do you have to ask?

"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
Copper has some value, at least you will pay with it a beer. According to a report I saw recently, if you demolish a house, the resulting rubble has copper and iron concentrations much higher than what you find in iron/copper ores.
You are unlikely to live in that house forever, and the next owner may not be as tech-savvy as you. Leave it for them. You could even be nice and upgrade it to RG6(Q). When doing home improvements/modifications, always look to when you sell the house, and whether it will add value or detract from the house.
I'm using the existing cable (RG6?) for MoCA throughout my house, rather than running Cat5/Cat6 everywhere (WiFi is good enough for my situation).
"and try to seal the various holes he left"
Don't keep the cable installation. Any future need for coax should be properly routed as you did with your networking cables. Holes in the walls are a no no. Most likely the rest of the cable install was rife with irregularities. Irregularities that can result in exciting things like flames after a lightning strike. Pull that garbage out and don't look back. Oh, and prepare yourself to discover Y connectors buried in the wall. You'll know what I mean when you pull on the coax and it is jammed in place. The install was likely not done by the prior owner but by a cable installation tech.
If you don't care about really high speeds, coax-to-ethernet bridges (designed for retrofitting surveillance cameras to IP devices) aren't expensive. If you don't have ethernet to those rooms then it's less hassle than running new wire and less prone to interference than powerline networking.
Log in or piss off.
And then you can either sell the copper inside or you can even make some homemade antenna with it if you're into DIY.
Autoerotic asphixiation?
Leave the cable, but I personally would use it to get reception if it runs to the basement by hooking up an antenna to for over the air signals. It may be neat to experiment signal processing with. OTA usb adapters are cheap.
Leave it there for 20 years give or take. It will come in handy, I'm sure.

You should be able to put a couple hundred watts through there.
This is the kind of comment that is making slashdot and other forums toxic. If you don't have an answer, just leave it be.
Showing off how "knowledgeable" you are by crapping on others without answering the question only fools newbies.
There are legitimate answers to this question, and maybe even some neat hacks. Sadly, they'll all show up below your waste of everyone's time.
Distribute e.g. 5V with it, ditch the wall warts. Make sure to measure voltage drop, but should be good for half an ampere or so.
The most essential things should be securely attached to that cable, with the loose end tied to the frame of your getaway car. When you give that final I AM LEAVING YOU speech to your spouse or longtime companion, throw that small carry on in the car, and drive off.
I'm not saying it will work, but I saw it in a movie once--something similar.
And this is Ask Slashdot, FFS.
RG-59 is *perfect* for distributing high-voltage.
C'mon, you know you'll want to.
Use it for that. Put a Put a ATSC Tuner card in a PCI Slot of your Domain Controller. Use the rest of the cable to run the rest to televisions, and attach the exterior input to a Terrestrial Antenna.

I would recommend removing all the wire from the house though. It's an eyesore, lets in spiders through the holes in the walls and is generally useless. Some people might suggest keeping the coax as a selling point in the future, but the people that can only afford Coax aren't going to be able to be able to afford to buy the house in the first place.
~ People that think they are better than anyone else for any reason are the cause of all the strife in the world.
Run ethernet lan over the coax. https://en.wikipedia.org/wiki/Multimedia_over_Coax_Alliance
If you really want to pull them, then use them to pull pull-cord through, and cover the outlets with solid covers. This allows you to pull whatever other cable you or the next owner might want through. I would then recycle the coax. But, it might be better to just leave them in place. If you ever decide to sell the house, perspective buyers may not be cord cutters.
With these cheap adapters you can run 5.1 digital audio over the cables. Just plug in one end to the coax out on your sound card, and the other to the input on an amplifier anywhere in the house.
Connect an antenna to the coax which will allow you to watch local broadcast TV.
I wouldn't remove it but decades ago when the cable guys were hooking up my house they gave me all the extra RG59 they had. It's really high spec stuff, low loss and designed for being outside in the weather.
I use it to connect to my amateur radio antennas. Yes, it's 75 ohm where all my radio stuff is 50 ohm. However, if cut to the proper length it will act like a 50 ohm cable at the frequencies the antenna is for.
The ratio of people to cake is too big

Yeah, I figured I should check to see if someone (multiple people) already posted this. Just make sure you push all your stupid raspberry pi, porn-filled hard drives, and linux journal magazines into a pile so you can all be easily disposed of. Make sure your note is short (avoid the word "manifesto") and mentions something about being concerned about your carbon footprint so you will get a remotely positive obituary.

You can get ethernet over coax devices, they basically run VDSL over the cable, about 200Mbit/sec.
I used it at my moms to get ethernet in another room.
Coax is horrible and near worthless as it is mostly non-recyclable plastics, foil and plated aluminum - no solid copper. My scrap yard will take it, but will not pay for it even if I bring in over 100 pounds of the stuff. I dug out 10 different phone and TV coax runs from my lawn a few years ago, pulling out every possible piece of wire just to be told I wasted my time. It was at least satisfying to tie the cable to the truck hitch and slowly drive pulling the cable out of the ground!
Abandon in place is best if it is not in the way. Remove easily removed sections that are drilled through walls and floors fully exposed, but hidden stuff just leave alone. External wall piercings are best filled with exterior caulk after removing the wire. Next best is cut the wire to the closest anchor point and leave it in the wall so a later installer can easily locate the hole and reuse the hole when replacing the wire.
TV aerial antenna to hide in the attic, or put onto a pole outside, since you may want local channels, and will need some type of connection so reusing the coax for this application is fairly easy.
Fab up a J-pole (or large dipole if that is what your receiver requires) for radio from some copper plumbing parts, or from some leftover coax. I get amazing reception with my J-pole with almost every valid frequency having a clear station on my radio. Not bad for some plumbing parts and a bit of wire. I made a J-pole from a piece of network cable before the plumbing parts and it was not nearly as good as 1/2 inch pipe, but was a superior antenna compared to the original stock antenna.

Laugh, it's good for you!
Use the coax as a way to distribute wifi in your house.
I don't know if this is the best solution, but it's one of the top ones I found when I googled "wifi over coax"
http://www.dual-comm.com/wifi-...
Have you ever considered seeing someone about your unchecked and displaced anger?
There are a couple of HDMI - over - Coax solutions out there if that floats you boat.
In fact there are off the shelf solutions for pretty much anything over coax if you'd rather pump audio or whatever round the house.
My home, like many, has a low-voltage panel where the incoming cable signal from the outside world is routed to the rest of the house . All the coax cables from every room in the house are connected to a splitter here.
The trick, though, is that cables run signals in either direction. When I ditched Comcast, I put an antenna (Clearstream 2V) in an upstairs room facing towards the broadcast towers. I added an inexpensive signal booster, connected this to the coax wall jack, and then in the low-voltage panel this became my source - I disconnected the "outside world" line, moved the line from the antenna there, and now all the rooms in the house can get a signal from that antenna for free OTA HDTV. This is perfect for a cord-cutter.
Just do HDMI over COAX.
Make omni antennae... for the kids, you kow... http://wireless.gumph.org/arti...

They have a point, as much as it pains me to say so. If you want a safe space echo chamber, go to Facebook. Just remember, usage of social media causes depression.
"Transparent" is a shit show that trades on every stereotype going. A man in drag is NOT a transsexual.
You can make nooses out of it and send them to Comcast executives.
OK, this is extremely clever and intriguing. Has someone here tried this?
I look at my router and the four antennae coming out of it. If I multiplex one of those antennae all over the house, is that going to reduce the power/interfere with some possible magic noise reduction tech in the thing for my central network? Does spreading things out more than make up for that?
Get yourself a few of these:
https://www.amazon.com/Actiont...
(They can be sold in single packs)
And you can use that coax to save you the trouble of pulling CAT5/6 to parts of your house.
Why aren't you encrypting your e-mail?
I'm a cord cutter as well. But sometimes I want to watch the new episode of the Simpsons as it airs. I installed a digital antenna in my attic and used the existing coax to run all the way back to my TV.
"Don't blink. Don't even blink. Blink and you're dead."
rg59 is great for low freq's. But horrible signal loss when you get to the upper end of MHz and beyond. Still it conducts a signal better than the atmosphere, especially considering the atmosphere of your house contains walls metal wood and other things that are nearly opaque to the ambient signals.
TL/DR; keep it, you have a great way to boost signals to areas w/ poor signal reception for ,,,,,, whatever you might need. Not great but still useful.
TL/DR; 2, it is better to not spend effort and keep a resource, than to expend effort to not have a resource.
You can use them to have an aerial in an upstairs room connected to your TV downstairs to get good reception for over-the-air channels. We did that when the last Olympics were on so we could watch because, a least in Canada at the time there were no good, cheap/free internet options which worked with an AppleTV.
Generally I still find live coverage of events hard to find online in a TV-compatible way although the BBC put coverage of the recent UK election on YouTube but they'd never be allowed to do that for the Olympics.
If you (or anyone else wondering) still need to run ethernet between rooms where you haven't got CAT cable, get a couple a DirecTV DECA for each end that needs an ethernet connection (make sure to get the power supply with each - you'll need them) and connect that to the coax cable.
Works great to get ethernet where you might not be able to pull in proper ethernet cable, and still provides decent speeds.
AC comments get piped to
You are the only rational answer. Now for a logical idea: use the cable for what it is good for; it doesnt need to be subscription service. I can modify my RF modulator to cast on channels other than 3 or 4 and now it can be used for monitors again. a remote control doesnt need to be infrared, it could be over wifi or some other spectrum to go tween walls.
Coaxial and a SWR meter and crimps means custom antennas for tranceivers.
Fourth - you're a fucking moron getting rid of a SECURE DATA DELIVERY CHANNEL. If you think your wireless is secure, you're ultra-fucking stupid.
He said he has Cat6 already.
Put cams in the room, a bed, sex toys, and rent them out. Skim off what the girls make in them. Profit!
By central network here I mean the central torus of the three remaining antennae of the wifi router -- I would expect one of three situations...
1. Really, you get most of your reception from one, two improves things by 20% or somesuch, the fourth adds just a few percent. You put 4 antennae on your router because it looks good.
2. It's 25% per. Remove one and you have 75% of your network power.
3. The router is designed to do clever stuff with 4, and removing one whacks out the whole system such that it's only half as good.
or perhaps situation #4...
4. Removing an antenna doesn't do much to hurt things, but multiplexing that one antenna all over the house confuses the hell out of the router and ruins everything.
Take it out to the curb, burn off all the old insulation, and recycle the copper. You can use old motor oil and a tire if it's the flame resistant type. Be sure to check with local and state authorities before attempting to do this to make sure you comply with all laws and regulations.
Most have long since departed Slashdot for other sites, and hence much of the posts tend to be crap. Heck, like this one. The current owners appear to be running the site into the ground to squeeze out whatever revenue they can.
Slashdot needs true editors who care about their craft (a long ongoing problem predating the current owners), better article quality submissions (way too many political / sjw agenda articles), less articles per day to allow better visibility, website revamp with some depth (being more than just an article aggregator), and better moderation. Dumping Anonymous Coward may be a good start. Though, I suspect the current owner may be constrained from doing that, since the post counts would likely drop to near nothing for many articles, illustrating how dead Slashdot really is compared to its early days.
All in all, Slashdot is still worthwhile for a quick read and an occasional post here and there, but for high quality discussion / dedicating much time posting, there are far better venues.
I've often thought about trying to directly route wifi signals over coax, but coax doesn't work so well up in the Ghz range, and you still have the impedance difference and extremely abnormal gain to compensate for. Besides that, digital audio or MoCA ethernet probably remain the most viable options.
75ohm coax is the perfect thing for running spdif digital audio over.
if you ever want to have high-fi sound send to remote room, spdif over coax is the way.
don't go thru amps, though; the catv amps are not useful and could mess up the audio signal.
and coax is better than toslink fiber; the fiber is not fddi or aqua OM grade glass fiber and the toslink plastic is junk. it won't pass more than 96k samplerate where coax can go 192k and beyond.

"It is now safe to switch off your computer."
While hams do prefer 50 ohm coax such as RG58 over the 75 ohm RG59 you have, nonetheless RG59 can be very useful to hams. Not all of them know it, unfortunately. When used as a feedline as a direct substitute of 50 ohm cable, the additional loss due to the impedence difference is surprisingly small. Homebrew antennas can also be designed to use 75 ohm feeds, an impedance which is very easily matched by any tuner. Some antennas such as magnetic loops actually use the coaxial shield as the primary active part of the antenna, so it really doesn't matter what the impedance of the coax is. Cable TV surplus RG59 is very decent coax. A ham radio enthusiast with an active mind would find countless uses for it. Dont't throw it away!
Fourth - you're a fucking moron getting rid of a SECURE DATA DELIVERY CHANNEL. If you think your wireless is secure, you're ultra-fucking stupid.
Why not let us know how you *really* feel.
SJW n. One who posts facts.
In many places, commercial firecode requires old [plenum] wiring to be removed as a fire hazard. Houses are more combustible and wiring adds little load, so it is usually your choice.
You could leave a good star network with head-end in place -- a future owner might want satellite system. Steal a run if the line makes a good pull-string to an otherwise difficult drop. But you might want to cut'n'seal some of that horrible outside surface-run. At least ground it well because that stuff is a lightning magnet. Check and maintain all service entrance grounds.
Rip it out, its an ant run, a bug trap, a place for water to collect.
Really, he doesn't know the state of the cable, and its been added later by the last owner. Time won't flow backwards, its not that everyone will switch back to coax in future by some random happy retro revival of coax, so its an unnecessary extra.
It won't add value to a house, sinces it an unfinished repair job.
Ripping it out, gives him a chance to see any damage an amateur installation might have done, typically wires packed with paper that's rotted and other nasties are things I've seen with these amateur wiring jobs. Better to fix it than leave it.
Woohoo!
RG-59 is approximately 20pF/ft, so figure out how much capacitance you have and use it in a distributed filter for any low voltage equipment fixed near your walls.
This kind of question belongs on Reddit not here. It's not news and nobody gives a shit about it.
As for toxic...slashdot has always been that way so if people trolling upsets you then just don't come here.
Not even site needs to be a safespace for the snowflakes
You can put voice, video and data over it at a blistering 45mb/sec
Or re-purpose it for a central TV antenna system.
If builders built buildings the way programmers wrote programs, then the first woodpecker would destroy civilization.
You do know that there's no such standard, right?
When I set out to wire my house for network, I faced a similar dilemma. When the previous owner ran coax, they simply drilled holes through the floor and ran cables up to the rooms. All the coax terminates in a utility closet where the cable company and the Direct TV dish enter the house.
I simply backed the wires out and ran them up into the wall along with the ethernet and, in some rooms, telephone wiring. I then terminated the lines at the wall and mounted them using those modular face plates that can be found at most hardware stores.
This way, if I sell the place, the flexibility for wiring in whatever is a selling point to a prospective buyer.
Coax is really low value at a copper scrapper. There is too much waste filler material for the copper to be easily recovered.
I agree, 99% of the time, but one exception I've run across in 3 different houses I've lived in now was telephone wiring.
With older homes, it's common to find a rat's nest of phone wires around a junction box in the garage or near the point of entry, as different residents required land land phones be installed in different places, or added additional lines.
Nobody ever wants to bother tracing old phone wires when installing anything new that needs them. Phone wire is really cheap and thin, so easy to run and to hide under baseboards and what-not.
If you're really motivated to clean up some excess wiring in a home, copper phone wire would be a great place to focus that effort. (Even if you don't think you'll ever do a traditional land line again, you may well do VoIP where the modem plugs into one of the RJ11 wall jacks to supply a dial-tone to phones in the rest of the house plugged into the other jacks. So having all of that functional and easy to trace is a plus.)
Sure, as others have said, resale value of keeping it in place... given that i'm looking to rip coax off the exterior (which I'd intend to replace with interior runs) which looks god-aweful, I'll understand ripping it out depending on the situation.
But... with a few adapters, you can use the coax for ethernet... the local Bell's xdsl solution converts XDSL to ethernet, then plugs that into a cable box that is also MOCA provider, which plugs into coax to enable tiny adapters at any remote TV to access the same channels.
the xdsl sucked, but the MOCA stuff looked interesting enough to investigate... turns out TiVo uses the same, and it's supposed to have decent bandwidth for reasonable adapter prices... just make sure you use a filter between the house and antenna, and you're good.
You think this is toxic? Wow. You've been asleep. It's not like he suggested using them to hang himself for being a fucktard liberal or Trumptard supporter or some shit.
There is still value in having local news for weather events, so install a local antenna in the attic and the value is back. Otherwise you can use them as analog RCA or digital coax or just recycle them.
Ive kept the old phone lines just to have a very cheap internet based phone which works through out my house for emergencies.
Strip it and take out the ooey gooey copper center. That is the only thing of value. Unless you want to put BNC connectors on it and run a daisy chain network (/s).
Why can't we go back to using jumpers to configure slot adapter cards? Why? I say!
There is a lot of bandwidth in those cables...
Like a lot...
But I don't know what else you could use it for other than for SDI.
I'm sure you could use it for data or as a replacement for RJ45, but still... I don't think that would be easy.
We bought an antenna at Radio Shack and a line amp, installed them in the attic, and used the coax to avoid paying AT&TCast whatever they're charging a month. Sure, RS isn't around any more but a local hardware store or electronics supply house will have these items. We can pick up more OTA signals than we have the time to watch. Any so-called `gotta-see' shows we can get at the library or video store (yeah, they're still around).

Fuck safety, just post relevant commentary. Tired of reading basement dweller bullshit.
Who said anything about safe space?
If you go to a store to buy a whatchamacallit, and the clerk says "you don't want one of those, they're trash" without any supporting argument, would your reaction be "oh, he's right! The thing I wanted *is* trash!"? .... I doubt it.
http://www.nuenergy.org/radiant-energy-diatribe/ Yea, people actually seem to cut off the outside insulation and make a backyard 'free energy' device.

Automatic dependent surveillance – broadcast. It is more benign than it sounds: just spend your days keeping an eye on your local air traffic (the transponder-equipped kind).
The point of a safe place is not to be an echo chamber, but to acknowledge a topic may cause emotions to get out of hand, so maybe it should be discussed seriously. Funny how often "maybe we should avoid be childish in this discussion" gets labeled as not adult behavior. Or how people like to view "let's find a way to discuss this in depth without just pissing people off" as wanting to not talk about things at all.
Frankly it would be nice if more people could find ways to discuss politics by discussing actual issues instead of quickly decending into name calling. But somehow things like not-naming calling, not being a dick, and getting things done is deemed childish these days, when there are still some big fucking problem that get ignored.
The copper price is high enough that homeless people steal copper wires, roofs and even break into live transformer stations, so you might get yourself some buck for the wires by selling to a recycling scrapyard that in turn sell copper by the ton to smelters. And you'll do something to the environment, too.

You really need to see someone about your reading disability. It's two posts above the one you replied to.
You are not guaranteed a place safe from unhappiness, unfairness or unsupportive people
"Transparent" is a shit show that trades on every stereotype going. A man in drag is NOT a transsexual.
You never know how long you'll be in a property; the next owner might not be a tech head and cable in every room might be a selling point. Unless you can get more selling it than it might be worth when you come to sell the property, leave it in the walls. If you want to get rid of the sockets, fine, but pulling cable out without having a way to easily replace it is a recipe for future sadness.
In short you are saying don't lower your home's value by getting it tagged as not wired for cable.
Also what makes you think tech heads are universally against cable TV or cable delivered internet? Yes the companies often suck but sometimes their tech is the better option. Personally I found cable to all the bedrooms useful. It gave me options for where to put my home office / game room. The modem being in the same room was convenient since I have the "work machines" behind a router / firewall on a different subnet from the wifi which is used for fun, family and guests. Locally the cable is a better deal than DSL which could accomplish the same thing since every room is wired for multiple phone lines.
Digital: Cable modem placement. Out-of-band distributed router management. Dedicated IOT network. digital coaxial audio Analog: Non-networked security cameras. Intercom system.
Fuck that. Pull cat6 and be done with it. Other than a few hardcore geeks nobody cares about fiber, but ethernet may be a selling point.
Or do one better, and install proper conduit so that it's easy to run whatever you want.
Safe spaces are total bullshit. They don't solve the problem - making every place more tolerant would, but if everyone is hiding in their safe spaces, how do you connect the silos? And safe spaces are pretty much the definition of echo chambers - no dissent allowed because you might *trigger* someone. If you have a problem that can be triggered, you shouldn't be hiding in safe spaces - you should be seeking professional help. No wonder social media causes depression.
"Transparent" is a shit show that trades on every stereotype going. A man in drag is NOT a transsexual.
To begin with, consider the quality of the installation. As others have noted, if what you have is cables run in a crawl space or basement and poking up through holes drilled in the floor by the baseboard, your best bet may be to simply pull it out and seal up the holes. It will be easy to replace if necessary. If you have a properly done system with the cables going into the wall and out through a wall plate, why not keep it? A future owner may like it. You can always put blank plates on the boxes if you find the CATV plates distracting.
Anyway, other possibilities for coax cables:
First, by having coax cables in place, you are already prepared for putting a cable modem anywhere the cable runs. This depends on the house, but if you want to be able to have a central location for a single router (wireless or not), you can put everything together in one spot where it is easy to maintain. For instance, for one of my sisters I found a suitable out-of-the-way spot in the middle of her house where I could have power, cable, ethernet cables, and telephone lines all come together in one spot (she has a VOIP telephone), all together, making it easy to reset anything that needs to be reset without having to go into anyone's bedroom, accessible at any time to anyone who needs to work on it, with a central location for the wifi so one router covers the whole house, etc. This would not work so well if I had simply left the cable modem/router in the corner of the house where the cable comes in.
Second: so, you aren't using the incoming cable for anything - not for cable TV, not for broadband, not for satellite TV - well, do you still have a DVD player or a DVR or something? If you hook this up in a central location, you can just use one for multiple TVs around the house.
Third: I'm not sure what CCTV uses these days, but that might be a possibility if you want to hook up a baby monitor or something.
Finally, as others have said - depending on how this was originally wired, it might be useful to keep the cables in place to pull in something new at a later date. Again, depending on the set up, you might want to leave everything in place, or you might want to cut out a bunch of a rat's nest of wires and just leave sections where it would be difficult to pull in something new.
That might not give you much to work with. The cables themselves are decent signal conductors, but the problem is that there just isn't much in the way of making a good connection to them other than what they were designed for. Otherwise you might be able to repurpose them for anything from a telephone line to a doorbell.
I'd just terminate them properly with wall plates where need be and leave them. Surely you aren't going to live in this house your whole life? As another mentioned, you can set up an OTA TV antenna and use them to run it to your TV.
I wouldn't remove anything, if you sell your house you can take a hit on the sale price for not having it wired properly.
Well, yeah. But how are you gonna do all that with a bunch of RG-59?
You can't see ANYTHING from a car, You've got to get out of the goddamned contraption and walk...Edward Abbey
If you put a RCA convertor on the end of your coax cable you can run audio or video on it to an outdoor projector or an audio system in another room.
but the question is kind of daft and short-sighted.
I think the post ruled that out. No desire to distribute TV
Still though, if the coax isn't an eyesore and one isn't the sort of freak that thinks fishing cables through walls and overheads is fun, I'd leave the coax. It may turn out that in 5 or 10 or 20 years there will be a need to send a few volts of DC or a low speed digital or analog signal to one of the places that the coax terminates. The RG-59 will be the "wrong" kind of wire to use of course. But it'll likely work.

I would leave the cable in place. If you ever install an outdoor or attic TV antenna, then the coaxial cable will make it easy to get the signal to multiple rooms. Many people still want cable hookup in every room, so it is good for resale value.
Pull them out of the wall, cut them so they're equal length, braid 6 of them together and try to terminate them into an RJ-45 plug. See if you can use them as a replacement cor CAT-6.
Is an ITU.T standart that allows high speed networking over thelephone twisted pair, electricial cable AND tv Coax with Similar Phy and LLC and MAC.
This has many uses:

Put your low speed gear in that network and reserve the Cat6 for highe(r/s) speed gear.
Or, as other posters said, leave it be, for if you sell the house latter on, you do not know if the new owner may want to have coax everywhere

He's already pulled copper. Installing conduit may or may not be practical, it's usually not a clean retrofit and most people don't want tracks down the walls. Like everyone else said, if the cable is ugly then you pull it, if it isn't then you leave it alone because why bother. Maybe it will have a use. I think a HD-over-Coax security system is a great idea, but maybe people don't want cameras in their house even if they [think they] control them.

When I got the house in 97, there were old coax cables going from the basement to the living room which I would assume was there for years before I arrived so probably RG59. We had cable TV but after a few years we stopped using the service and took out all the coax on the outside over the years of renovation. When HDTV came to Canada in 2011. I researched and got an OTA antenna on the roof and got a line running to the basement where we placed a signal booster/splitter. Since that coax cable was already running from the basement, I hooked it up and found it worked. No need to run a line and saved myself some work.
If they were fished in the wall, often you can use it to pull CAT or fiber. You can use them for all sorts of low speed busses (CAN, I2C). You can just leave them, if you ever sell the house or rent it out the next person may appreciate if you don't cut them. If necessary put them in a nice box with your CAT wire. There are also various AV solutions that use it to distribute even 4K HDMI signals, from a signal perspective, terminated properly and for short distance it is an alternative to fiber.

I have never bought a "properly wired" home - a "properly wired" home, by my definition for the past 20 years, would have cat 6 (5 in the earlier days) distribution throughout with a central patch panel, or two.
Other people may prefer co-ax for cable TV, but the balance is shifting my way - might reach parity in another 5 years or so.
Sure, but for most people a properly wired home is telephone and coax run to most rooms. Almost all non-techie people use wireless. We're a unique crowd here.
Unless you want to put BNC connectors on it and run a daisy chain network (/s).
Ethernet over coax hasn't stood still since the decline of 10 base 2: you can get very cheap baluns which will give 100mbit half duplex ethernet over coax which is fast enough to match all but the best home internet connetions. If you're pepared to spend a bit more, you can get gig-E transceivers which can send it p to 2.4Km over coax.
SJW n. One who posts facts.
wrap it around your neck and jerk off to the latest release of Rust
my captcha word was "spectrum" haha
That might be load-bearing coax. Better get that house of yours inspected properly before you start yanking out the cable. I once almost collapsed a house on top of me just by tapping a rusty pole with a toy.
Years ago I used this method to get network access when some numbhead decided to move my office to the other side of the site. Luckily it was a TV station so there was plenty of point-to-piont video coax.
To-ma-to? To-mat-o? Useless comments are still useless.
MoCA can do ~700 Mbps over coax.
Use them to pull fiber cables through and you'll be ok for the future.
Your point about resale is exactly why the coax should likely be removed. The OP mentioned holes rather than wall plates. I've seen simple holes drilled through the baseboard. Not proper practice. Most likely his house has a typical installation. Which is to say a horrible mess that completely disregards all notions of proper wiring. That is what I have normally seen unless the home owner went back and replaced the original installation or had an electrician do it. In my house the existing coax was routed in insane fashion with a host of violations. The class of coax wasn't even suitable to connect to a digital TV antenna. In my parents house they had their coax redone during an expansion and remodel. The existing coax install was a comedy of horrors and also not of a class suitable for digital broadcast. Most cable installs are this way. There was even a feature film made about the ridiculousness of the cable guy. It had basis. Most cable guys had no particular know how and were wrangled up at the lowest cost for an employee that might be sober on the job most of the time. The greatest likelihood is that the OP's install is horrid and faulty for cable tv much less any other purpose.
Also basement dwelling "experts", please be aware. Wire crossings without appropriate clearance in walls is NOT appropriate practice. Removing old useless crap is often REQUIRED in order to install new wiring properly. First action is to identify old wiring and determine whether your new run will have clearance. CUTTING THE END OF THE CABLE AND PATCHING OVER IS SHODDY PRACTICE ONLY ADVOCATED BY THE INCOMPETENT. People who properly install wiring despise you. The cable could have been pulled prior to patching so a COMPLETELY USELESS cable could be removed. But now in order to install the wall will have to be reopened. Wire carries current so removing random unused wire is good practice. You can only really assure proper clearance if there is only conduited wire or wires following known routes. You detect an old wire run you either have to avoid entirely or remove entirely. Chin rubbing and hoping for the best is not good work.
If it's a through the wall installation push them back into the wall and put a blank plate there. Make a map of your house. Mark what switches control what lights and outlets. Map the now hidden coax. Pump digital audio over it? In any case the value of your house will be improved if the coax is in the walls.
If it is not in the walls, pull the staples, and coil it it. cut it as little as possible. Sell it on craigslist so someone else can reuse it. Or an amateur radio flea market, 75 ohm coax is useful for making some types of antennas and even shorter lengths can be useful. Lots of opportunity for reuse. And as a last resort rather than landfill it sell or give it to a recycling place.

Beam your old Atari to randomly placed monitors in the house.
If you look at all of the things you can run over coax and you are already using CAT5/E/6 for Ethernet, well just run any of that other stuff over the Coax. I mean:
1. Pipe uncompressed video and/or audio over it from one room to another. This could be in terms of home entertainment center stuff is mostly tucked away in another room or computer is in one room and console is in a different room. Maybe even do a multi-seat setup with a computer in one room and have the second console in another room / hooked to the TV.
2. Have a camera network with its own dedicated bandwidth.
3. Send free terrestrial TV over it from an antenna.
4. If for some reason you get bored of being a cable cutter / decide you want satellite TV / other people in the household are demanding it and you cave in to demand, you may just find those cables in use again.
The reality is most probably is once you have Ethernet as you state and you have already decided that there is no point to cable TV, most potential uses of coax are going to cost more than they are probably worth to you. If push comes to shove, a prioritizing Ethernet switch will eliminate the need for a second data channel for time sensitive things and if there is something in your home computer or entertainment center that is noisy, a quieter fan is usually cheaper than extending video and audio along with IR signals over coax. Also if you saw a need for more data channels to a room, you probably would have installed extra cables when wiring up the Ethernet cables.
One thing that is not clear about your description is there is no such thing as CAT6E. There is CAT5e, CAT6, and CAT6a. If you have CAT5e as opposed to CAT6 or better (and I assume for CAT6 [not CAT6a] the distance is less than 55 meters), then maybe one day you will want to go up to 10 Gb/s and find that CAT5e is not going to do it, but hey someone just released a 10 Gb/s over coax MoCA adapter. (Currently the fastest MoCA Ethernet adapters get to ~900 Mb/s in one direction [UDP], but there are cable modems that can push multiple Gb/s on the market today, so the possibility is there). In short if you find one day your wired Ethernet plant is not up to task and you don't want to go through the hassle of pulling new cables, maybe you find yourself going over coax instead. Of course I would just use the under-performing cables as pull strings if I could.
..as others have mentioned, it just keeps getting faster, and goes further...

Don't pull it off, specially if you don't know how it was installed... that is, unless you need more space to pass something else.
Generally a good idea to just keep cables there even if you end up not using them to avoid unecessary stresses and damages to the structure.
I also cut the cord a long long time ago and since the apartment was new, I ended up pulling a coax out of one room to make room for ethernet. I expected to pass more than one cable, but then I didn't. And then I ended up having to pass a coax once again because the office room turned into a guest room and I decided to at least leave open channels available.
Other than that... perhaps a multi room sound system setup? If it's something simple, coax should do the job.
agreed. old coaxial cable is not worth your time. if your time is worth anything, throw it in the trash and let the garbage people decide.
Dumping Anonymous Coward may be a good start.
Nope. Anonymity allows expression of unpopular positions/facts. If you want rigorous discussion then anonymity is necessary. This is funny considering you posted as anonymous.
All in all, Slashdot is still worthwhile for a quick read and an occasional post here and there, but for high quality discussion / dedicating much time posting, there are far better venues.
Such as?
Somehow our college accidentally broadcasted parking lot security cameras through the cable. So, that might be a use if you're supper paranoid.

So are useless posts, yet the poster AND mod turkey on duty both missed on this tupid submission.
What can I do with this box of old used rubbers under my bed?
Fourth - you're a fucking moron getting rid of a SECURE DATA DELIVERY CHANNEL. If you think your wireless is secure, you're ultra-fucking stupid
While most of your points are valid, you don't have to be a dick about it. Also, if your attention span or reading skills were at least adequate, you would have noted that the original poster said (s)he already has a "SECURE DATA DELIVERY CHANNEL". They quite clearly stated that they have "already run CAT6e everywhere".
You can utilize that cable for low voltage DC to power all kinds of things. We manufacture a 12V DC UPS that can be powered up to 46' over coax. www.espicorp.com At the very least, leave it installed.
I definitely don't see the reason to wire with cat6; cat5 is more than enough for 99.9% of what people are using in a house. I'd run fiber + cat5 to the TVs and anywhere else you can forsee enormous bandwidth; for everything else there's wifi and cat5. Cat6 is expensive and 10gbe is cheaper as fiber anyway, as 10gbe copper is power hungry and expensive as hell.
If I were to wire a new home I'd run a cheap vacuum cleaner conduit from the basement to the attic; all drops for any upstairs rooms would go through the conduit, making all the upstairs runs *trivial* to change/upgrade if need be. I'd have a dedicated run (power and network) for a main floor and upstairs closet (a central one on each floor anyway) for wifi, the power is there so it can be tied into the same UPS that's keeping your basement infrastructure powered.
"way too many political / sjw agenda articles"
That's code for "way too many articles allowing criticism of Trump and other right wing totems".
Use it to distribute video around your house.
HDMI is totally useless and doing HDMI over CAT6 is a pain.
The pro's use SDI which runs over coax cable. Any live broadcast or pro video setup will use SDI.
You can easily convert from HDMI to SDI and back again and it will go 120m.
It supports any resolution up to 4k and 16 channels of audio.
Use the class for what it was designed: broadcast distribution of video. DVB-S to DVB-C transmodulators are relatively cheap now, and FTA satellite signals should be available across the USA on Ku-band (small antenna). Why not set up a few receivers and transmodulate the signals to DVB-C for reception at TVs around your house? Only do this for free TV, so there's no recurring cost. I suppose the North American variants of the DVB standards should also be available to use if you have TVs with built-in tuners.

*You* seem whiny
Curious, do people like you really have nothing better to do but create "toxic" posts on various sites?
Who said anyting about the world being "nice and fair"?
Do you have a suggestion on what the OP can do with his old Coaxial cable, or are you just wating everyone's time?
Second this post. you can get coverplates to "hide" them and even paint over them so they are less visible.
unless this is your final home, you dont want to do things like rip it out and then leave a mess for the next owner to try to get it back in. it isnt harming anything having it there is it?
No, there's also too many articles about transsexuals and other deviants.
That's rich given you have little tolerance for somebody with a different opinion from yourself, and you advocate banning anonymous speech. Your alias is King Echochamber.
moca networking?
How is saying safe spaces are a way to avoid fixing the underlying problem in any way related to my wanting to ban anonymous speech? Oh, right, they actually go hand in hand. You should have to stand behind what you say. Anonymous speech prevents that. Same way that hiding in safe spaces avoids confronting the problem you're hiding from.
I see logic is still something you're only vaguely familiar with.
And when it comes to different opinions, you've already proven you lie at the drop of a hat, and contradict yourself in the same thread. And you're still just a pitiful fat aging virgin troll, and will be until you die.
"Transparent" is a shit show that trades on every stereotype going. A man in drag is NOT a transsexual.
what are the windows made of?
or you could ignore it. *gasp*
/. isnt a store. you're not buying anything. no one cares if you buy trash.
At worst it's a useless bit of wire you can later use to pull something more interesting through.
However, having been in a similar situation recently, I decided to do something more esoteric/stupid.
I rerouted a bit of the coax going to the living room to the office instead of the cable junction box, and crimped BNC connectors onto the ends. Then I took a couple of old 10Base2 hubs and turned it into a thinnet link.
Why? Because.
Is it fast? Not really.
Faster than WiFi? For us, yes, actually. You can stream Netflix et al just fine over 10Mb ethernet. (Maybe I should upgrade the WiFi...)
Could I have run Cat5/6 just as easily? Yes.
Should I have? Probably.
Will I just make it normal Cat6? Probably some day. The Nintendo Switch has a beef with the 10Mb hub, maybe it's trying to force full duplex? (workaround: put a Fast Ethernet switch between the two)
Magnets are two-faced. No choice for sugar but what choice could there be but to drown in coffee or to drown in tea...the frustration of being inanimate.
The ability to post without logging in is one of the major reasons I still visit Slashdot. Other sites demand that I remember a username and password, and I just don't give that much of a fuck. But I'll fire off a quick post on Slashdot without a problem. Or sometimes spend upwards of an hour on one. It depends on my mood, but not my memory or give-a-damn. That's important, and it's what the web should be. Not a locked-down, super serious business, humorless enclave of people who demand an accounting for everyone's opinion. If you want that, you're looking to join a political party, not all of human society, which is the approximate limit on who can post on Slashdot.
TL;DR: If you don't like anonymous postings, you're doing the internet wrong.
Nobody wires up telephone anymore. Even home builders only bother with it because the building code requires at least one phone jack installed and wired back to the demarc panel/box/punchblock.
I bought a new house in 2014 and there's a phone jack on the wall above the end of the kitchen counter. It goes to a punchblock mounted to the wall next to the electrical panel, which has a pigtail over the sill. If I wanted phone service, the phone company's installer would put a demarc box on the outside of the house and hook up to that pigtail and I'd have phone service. That has, obviously, not happened. And won't. Maybe the next owners will care. But probably not.
Us the old coax to make long range antenna for Wi-Fi.
Has never built a house.
I've never seen coax put through conduit in a house allowing you to use it as a pull wire. At best, it's snaked through holes drilled through the joists and floor boards. At worst, it's stapled to the joists. Typically, cable fasteners are used.
Any way you slice it, you're not going to be able to pull it.
That being said, if you buy a house with an unfinished basement, do yourself and every future home owner a favor, and run 1/2" EMT or PVC from your basement utility room to every habitable room of your house.
Coax has some advantages over regular cable. The most important one is EM shielding. This means that there might come a time when you start getting wireless routers with coax-connected antennas so that they can cover entire buildings instead of having to set up multiple routers. That I'd say is the single most probable use of coax in the future, as long as you're not getting internet over coax ofc. (internet over coax is quite nice, getting 100/20 MBS here, and regular copper has too much signal interference where I live for any speed over 20/1.5 (and it was unstable as hell))
I bought 3Km of coax to use as a delay line a couple of years ago. And I was getting paid. So there.
*You* seem whiny
That's fine, I don't really care what I seem like to you. *You* seem like someone who would jump to a conclusion based on a couple sentences.
But what do I know? I'm just some Anonymous Coward.
You have no idea what I have that's better to do or not. Maybe I do, maybe I don't. Either way, you let this get you and I enjoy making sensitive twats squirm.
And to answer your question...he should leave it there. It's not hurting anything and it's not worth the price of metal to try to pull or open up the wall.
Also, I enjoy wating people's time.
Nothing quite like the sound of properly cured and aged cable. Makes the tone warmer, the highs less harsh, and the bullshit greater compared to the fresh stuff that hasn't been properly cured yet.
You could always leave it... MoCa 2.1 is really reliable and is 500Mbit or 1Gb bonded. In my experience a completely empty network with no actual Cable TV signal comin in can easily achieve that bandwidth with ethernet like latency , unlike Ethernet over Power, which is more like wifi levels of latency.
it's super cheap and some TV's/DVRs etc support it natively with no need for an adapter.
Even Moca 2.0 would be good for a network where you have no Cat5e.
I have a personal Windows domain controller which manages the Windows side of the network. I thought everyone had one. It's no more out of the ordinary as my Linux PKI, DNS, and LDAP servers and oh good god do I need to get laid.
You can use it for HD-SDI and run 1080p60 video over it using relatively cheap converters like these:
https://www.monoprice.com/prod...
https://www.monoprice.com/prod...
Although since SDI is using BNC connectors, you'd either need to install BNC sockets on your coax, or you'd need to use an adapter like this:

Does one covfefe before poated?
RG59 is marginal for even digital cable, CATV has been using RG6, generally quad shield, for a couple decades now. Oh, and CAT6e doesn't even exist as a standard, so we know that part of the question was there just to make the OP sound like they knew enough to ask the question.
If old wire of any type is pulled into residential stud walls you can't just pull it out, and if it is stapled to the baseboard then it can be easily replaced with the appropriate wire for the task at hand.
If the question is actually looking for a use for the old wire, then the answer is "if you have to ask then no". If you had the skills and hobbies to repurpose it you would know before you asked.
I know I am an old retrogrouch, but these faux techie questions really make me miss the days when hackers used soldering irons and nobody tried to establish their geek bona fides by asking questions on an internet forum.

You can use it to distribute HDMI@1080p using cheap SDIHDMI adaptors that are available from Ebay.
It should be noted that SDI doesn't support HDCP but you can get round this using cheap HDMI splitters also available from Ebay.
There are also many cheap SDI cameras available also from Ebay that you can use as an SDI source.
For Coax, Internet is the best use of the cable post TV signals. Those DirecTV adapters cost you $5 per end and you can start running long range routers/repeaters with this stuff. Plus, these cables fail less likely than Ethernet.
15 years ago, I had an idea for low-cost in-home distribution of HD video that I wanted to try in the worst way, but didn't have the resources or knowledge to actually build it myself.
The general idea: take the three HD analog component video signals, and modulate them as wideband FM. Do the same for the two SD S-video signals (approx 5MHz apiece), the SPDIF signal (approx 3MHz), and the stereo audio (except do the stereo audio just like FM radio, on a frequency like 89.5MHz so it can also be tuned directly by a FM radio). Now combine all of those wideband FM signals, and inject them into the coax (for obvious reasons, it would have to be dedicated to this task & couldn't coexist with signals from the cable company or satellite TV). Maybe add another copy of the SD signal, modulated as NTSC channel 3, just to make it available on other TVs without needing an additional box.
At the other end, decode the wideband FM signals back to component video, s-video, SPDIF, and analog stereo.
I figured that a single 720p60 or 1080i60 source would need about 200MHz total, which would be totally do-able with in-wall coax. It would have required dedicated coax (ie, it absolutely could NOT have shared a coax cable with cable TV or satellite), but circa 2005, that wasn't a big deal anyway... the house had the old RG59 cable in the walls that the original builder used (that I would have used for this purpose), and both Comcast and DirecTV ran new RG6 cables anyway.
Why was the s-video part so important? Because I always used HD cable/satellite boxes, even for my non-HDTVs, and used the box's S-video output (with the HD channels) instead of the SD channels to get DVD-quality TV instead of blocky, shit-quality TV.
Some grades of coax can be used for amateur radio equipment.
Why bother with Cat6e? You aren't getting much of a benefit over cat5. If you want to be 10GBase-T ready you should have put in Cat6a, not Cat6e. Plus go with the shielded version as it is smaller and easier to work with.
Put up a TV antenna, tie it in with the coax, and you can have free HDTV from over the air stations. If you live close to the city where the stations are, you will get better than cable TV quality reception. We live 55 ,miles from the big city where the stations are located and get better than cable quality on most of the 20+ stations we receive. (We do use streaming media to the TVs in the house also.)
What's the harm, if you sell the house who says the next owner will be a cord-cutter.
Get a QAM box and a coax distro in your basement and run video to every room. TV's still have coax inputs. This way you could have broadcast HDTV, BluRay, DVD, or even an Apple TV in a single location and have your own broadcast network. All depends on how much video content you consume.
My advice is dont remove the cable. Put up an outdoor antenna, hook it up to your cables, and you have 20-30 free channels, use it to get free OTA TV and pipe it over your coaxial cables. With the upcoming ATSC 2.0 standards, digitial OTA is going to get even better with data streams, and more channels. Its free, so why not take advantage of it.
There are HDMI over coax adapters. Coaxial cable is great for digital data so you can use such things to repurpose your cables for digital .
MOCA also came to my mind, which allows you to transmit your own data around your house using your cables, probably video and other data. If you have a PC with with a tuner card in one room,it may be becoming possible to have a MOCA adapter to send the data to other rooms over the cable.
I have seen Moca adapters for connection Ethernet to the coaxial cable and sending data over the coax using Moca. Actiontec has some of these on sale.
Coaxial cable has a very high bandwidth. Combined with modern chips, what could the data transfer rate be? A lot higher than trying to squeeze data over twisted pairs, I bet. With todays technology 1 Ghz of the cables bandwidth can be used. A coaxial cable is sealed so you can put high frequencies on it without interfering with transmissions over the air. Its still a very good, viable transmission medium. Im surprised its not used more for computer networks.
So many freaking stupid comments on this question.
The simple answer is either (a) leave it alone or (b) make use of it.
I moved into a house that had at one point been a four-unit. During the conversion to single-family though I left all the coax in place... and there's a LOT of it (since at least one of the tenants had satellite and others had cable). I figured at the time that I could use the cable to pull through cables I did want in walls I didn't demolish.
Well, two years later I decided to just use it. I have cable internet, so the coax is obviously used for that... but did you know you can also bridge gigabit Ethernet across coax?
https://www.amazon.com/gp/prod...
These are the exact units I bought... I got two of these two-packs. Using the existing coax I was able to hook up to my rack in the basement (my lab) and run Ethernet directly to the two bedrooms on my third floor which are primarily for (a) my son and (b) guest room. Yeah, I have great WiFi as well thanks to also running a pair of Ubiquiti Unifi AP's (one run off my core switch on the second floor of the house and the other run off my switch in my basement rack) but especially with brick houses like mine (130 years old) sometimes the WiFi can be a bit slower than I'd like. As a result, I have hard wires where I want them.
I also have one of these bridges still sitting in a box if and when I need it.
As for the performance... the speeds aren't quite gigabit. I get around 850Mb/s or so pretty consistently to my basement. I haven't tested the performance in the bedrooms but my son never complains about his Internet speeds on his gaming rig and it's plenty fast that I have all my Windows computers set up to do their "File History" to my ZFS-based file server.
20 Or so raspi streaming Pluto tv into 20 rf converters set to separate channels, use splitters to combine the signals and a few cable amps to push the combined mini cable station to the house.
One of the universities I visited used old coax cable runs in their dorms as wireless antennas. The jist of how to do it was to attach a low power power amp to the output of a typical router with support for external antenna. Then wire the gained end of the power amp to the coaxial cable. You have to use a second power amp (or the other half if has two channels) to gain the return from another coax cable to receive signals. The setup isn't exactly simple.... but it works fairly well if the house gets poor reception otherwise. In my univeristy example, they used one floor's cabling for transmit and the next floor for receive, repeated until out of floors.
Rather than run more network cables, or setup a VLAN, use Ethernet over coax adapters to connect security cameras together on their own physically separate network.
Use the Micro ZMS made by Zapelin to convert and inject iptv channels directly into the coax network. (only interesting for countries with DVB-T/ISDB-T compatibility). In fact, Hotels or large residential complexes, condos who do not want (or can't afford) to rewire the whole resort with network/fibre cables could still distribute iptv content to TV's throughout the building. Of course, this is not an option for the home ;-)
This. There's no reason to mess with them.
When we bough our 110+/- year old home, it was wired for telephone and cable in every room. We are also cable cutters and didn't need the room-by-room wiring for either system. I pulled the most offensive pieces of coax and lengths that ran to rooms that we would least likely ever need/want a TV. I left the one in the living room and used it as a connection to a roof mounted HD antenna, now we get 25+/- free over the air TV channels. The rest I bought weatherproof couplings for and also purchased coax to ethernet converters for either end and ran it through a buried conduit to my detached garage. The telephone lines were mostly just pushed back into the wall and the holes plastered over. I'll grant that these may not be the most resale friendly choices, but If all goes to plan, it won't be our problem...

I solder RCA interconnects for short run RCA cables.

You can Get a radio operator license and use the coaxial to hookup a radio antenna for a radio.
Two solutions I've used in the past for old copper cable...
A> Use it to bring in the signal from a roof mounted digital TV antenna.
B> Make a short wave antenna for the old radio out in my workshop.
C> Sell to a recycle company for enough change to take the kids out for burgers. BTW, you get a better price per pound for the copper if you burn off the insulation first.

From the link:
"A +Plex media server on my network serves out video to an +XBMC distribution running on the +Raspberry Pi where the video is then sent to an RF modulator and then combined with all the over-the-air channels that we happen to get. The result is that we can tune into a specific channel (set at the modulator) on any TV in the house and watch an endless loop of, in our case, Simpsons and Futurama episodes. You get the sense of it being a normal TV channel, except that it's only stuff you like and there are no commercials."
After the question was posted I came across an urban garden where old cable wires had been strung to form a horizontal trellis for climbing vines plants (squash etc). I have a pic but don't know how to post it.
the value is that it's in the walls already.
BNC terminated coax works fine for HD-SDI video if the installation is done properly
Do you think you can repurpose the lines for cell phone boosters?
...enjoy wating... Is it "...enjoy waiting..." or "...enjoy wasting..."? Make up your mind already. You are wasting my time while I wait for your answer!
Thanks for letting the imbeciles know

You know what? Go fuck yourself.
If you're going to be contrarian for the sake of trolling, leave. We don't want you here.
I just read Slashdot for the headlines now because the comments are a cesspit of stupidity.
What exactly marks a rooftop antenna as digital vs analog?
If you act like an asshole, and I call you on it, and you respond with something about no guarantee of 'safe spaces', then thanks. I know you are not worth any more of my time.
You really need to see someone about the fact that you're a complete fuckwit.
How is saying safe spaces are a way to avoid fixing the underlying problem in any way related to my wanting to ban anonymous speech? Oh, right, they actually go hand in hand. You should have to stand behind what you say. Anonymous speech prevents that. Same way that hiding in safe spaces avoids confronting the problem you're hiding from.
If you say something unpopular, no matter how correct it may be, you can be subjecting yourself for hardship. This is EXACTLY why anonymous speech needs to be protected, and if it isn't, it contributes directly to the echo chamber that you claim to be against. Case in point: Try saying anything even slightly against the grain at Evergreen State. You'll be subject to anything from constant harassment to physical assaults if you do.
I see logic is still something you're only vaguely familiar with.
Far from it, rather democracy is something you're only vaguely familiar with.
And when it comes to different opinions, you've already proven you lie at the drop of a hat, and contradict yourself in the same thread.
That's rich; I've done neither of these things while you've done both in the same post.
And you're still just a pitiful fat aging virgin troll, and will be until you die.
Umm...everything you've just accused me of is something you're guilty of. Seriously, all of it. Furthermore, I'm not anywhere near as old as you are.
Even the cutting-edge Verizon FiOS uses RG-59 for the service entry if it exists, or RG-6 for new installations. This cable's capacity is more than double the Verizon FiOS maximum physical speed. Not bad for the 40-year-old dusty cable in your house.
RG-59 cable is also perfectly capable of carrying more than 1 GB data everywhere in your house via the MOCA standard. No need to pull new Cat5e or Cat6 cable for gigabit internet throughout your house. The MOCA/HomePlug adapters are cheaper than pulling new cable.
There is literally no good reason to remove even obsolete RG-59 from your home. The sole exception is when you wish to deliver satellite television inside your home. That requires RG-6 cable, but only for the drop from your satellite dish and its switch to your satellite receiver. For multi-room satellite service you might not even need more than that first drop. Read on.
Even if you use satellite television, the multi-room DVR of satellite TV and most cable companies (including FiOS) uses MOCA to transmit the video, and it works perfectly fine over ancient RG-59 cable.

Yes, and coax can be an abnormally low-value scrap partially because scrappers assume all coax is copper-clad steel instead of pure copper.
There's no real performance value in having pure copper coaxial cable, even for satellite television, so nearly everything is installed with copper-clad steel cable, which is cheap steel with an electroplated copper coating. The very rare exception are the satellite internet providers WildBlue, Exede, and HughesNet Jupiter, who have an abnormal fixation on pure copper RG-6 cabling even when copper-clad steel is superior. You find these in mostly rural markets.
The cheaper copper-clad steel cable has the same RF performance and has superior power-carrying performance than pure copper because satellite TV requires the LNB to be powered with 13/19 volts at 500 mA, and satellite internet requires even higher current. Copper-clad steel is a much stiffer cable and can be easily identified due to its stiffness and the silvery-white colored center you can see when you cut the cable.

If you're not prepared for the repercussions of your speech, then you don't believe in it all that much to suffer the consequences. It's the same as people who take part in a protest and then get all upset when they're arrested because they don't want to go to jail - useless cowards. They lack the courage of their convictions.
And I never said you were older than me - if you were my age, you'd probably be wiser. But you'll die before I will, so I don't give a fuck. All you guys who are living the movie "40 Year Old Virgin" have already demonstrated your total lack of social skills.
"Transparent" is a shit show that trades on every stereotype going. A man in drag is NOT a transsexual.

I'll tell you what: Go to Pakistan and tell everybody about how you think it's awesome to remove your genitals and dress like a woman. Let's see just how well your convictions hold up. And I'm going to add this: Give me your address, and next time I'm in Canada (if it should happen again, but honestly after going to some bore's asshole called Toronto, I don't really think I want to go back there) I'll happily and loudly say what I think of your sorry trans-fat genital-less silicon-poisoned butt-lifted ass, Tom, and you're welcome to try to sue me but it won't do you any good: The US does not extradite anybody (including foreign citizens) for actions protected by the constitution, nor does it enforce foreign lawsuit judgements against the same actions (this is something the Obama administration with a democrat dominated house and senate did, by the way.) Unlike Canada, we have this thing called the bill of rights, which among other things not provided by your government, gives us free speech and protection against compelled self-incrimination.
And I never said you were older than me if you were my age, you'd probably be wiser.
I'm easily far wiser than you are. Every time I argue with you, I do it on scientific grounds, and you always counter with logical fallacies, speculation, and total bullshit.
But you'll die before I will, so I don't give a fuck.
Hmm....well, I have stage 4 chronic kidney disease so there is some merit to your argument...but only just.
You're a narcissist, which has a suicide rate 50 times that of the general population, and you're a trans-fat, which has a suicide rate far, far higher than that even. Combine the two and...I'd give you...hmm...about 5 more years? Give or take a year; it just depends on how long it takes for you to realize that you aren't fooling anyone. But if you're able to remain very good at self-delusion like you currently are, then maybe add another two years before you OD on heroin while trying to amplify your delusions of yourself as a Mary-Sue character.
As for me...I'm in overall good physical shape, which usually means a good outcome for people with my condition...so...another 40 years? Give or take 5, unless UCSF's iRAD (or something like it) is successful in the long-term, then I can possibly live into the 80's. And unlike you, I won't be closeted about the fact that some of my organs are no longer intact.
All you guys who are living the movie "40 Year Old Virgin" have already demonstrated your total lack of social skills.
My "lack of social skills" as you put it is a symptom of PTSD. While you feign harassment and persecution all the damn time, I've actually lived it. You're just a dickhead narcissist with a victim complex, so you make it a point to talk about it all the time, but actual victims don't do this; they prefer to never mention it at all, especially in the case of sexual harassment, and will only occasionally do so if they deem it therapeutic (i.e. group therapy.)
In fact I often hang out at a local bar with a group of friends, and occasionally one really manipulative narcissistic woman (real woman, mind you) that nobody really likes comes around and talks about how she's been raped many times in her life, because she likes the attention it gets her (that is, until people get sick of her.) One time I said to the group that she's full of shit for the exact reason I'm telling you that you're full of shit, and I specifically mentioned some psychology articles I had read about the topic. And you know what happened? Two (real) women pulled me aside (at different times) an
You're a real fuck-up, you know that )I suspect you do). I have no reason to go to Pakistan or India. However, I would have zero problems in Iran, or Cuba.
As for your "psychological insight", you have none. Unlike you, I don't cherry-pick articles off the web, I actually use medical specialists. Anyone who takes medical advice from you is even more fucked up than you are.
You really can't accept that someone can be happy changing sex, can you? You're one of those guys who sees me as being a "traitor." Just goes to show how fucked up you are that someone else's happiness is a threat to you.
As for attention-seeking, you're the one always indulging in trying to get my attention by stalking my posts so you can turn the conversation off-topic because you secretly have a thing for transsexual women that is so obvious it's not funny. Anyone can verify this by checking your posting history, stupid tranny-chaser.

And yet you always insist that I go to Canada...Hypocrite much? But that is beside the point. The point is that forbidding anonymous speech about unpopular opinions creates undue hardship no matter how right or wrong those opinions may be, especially in the case of whistleblowing, where retaliation is very common. If your own country banned anonymous speech, it would easily turn into another China. The fact that you are blind to this either speaks volumes about your stupidity or just says that you're a nazi.

It's funny you say this, because just yesterday my psychologist (who has been practicing since 1980) commented to me that my knowledge on this is pretty good for somebody with no relevant degree, without me even soliciting such a comment. It probably helps that I read a lot about my own conditions.

If that was actually the case, there are far more (and honestly, more interesting) targets than you on slashdot, and yet my discussions with them always remain short and civil in the event that they rarely happen. But you wouldn't know because you gave up civility a long time ago. Anybody who attacks personal liberties and demands authoritarianism the way you do is inevitably going to get the same response out of me. You being a trans-fat is notwithstanding and is just yet another ad-hominem on your part, which seems to be your get out of jail card every time somebody proves you wrong.
Why would ANY Canadian want you to go to Canada? Keep your fuckups within your own borders. Bad enough we're getting 150 of refugees illegally entering from the US every day.
As for non-anonymous opinions creating hardship, that's a bonus. It filters out the noise, as then only people who are willing to put their money where their mouth is will say anything. You are an excellent example of the torrential flood of shit that comes with anonymous and pseudo-anonymous speech from cowards.

You mean somebody besides yourself (on multiple occasions)?

Most of the insults I've hurled at you are just an echo of things you've said to me, only I do it much better than you do. For example, the whole trans-fat and buttlift picture only came after you started labeling me as fat. Do I troll? Yup, I've never denied that, and the way I do it isn't appreciably different from the way I bust my friends' chops and they do the same thing to me. Hell, one time I offered a gesture of good will to you, and you just verbally spat in my face. Say what you will about me, but I'm not the bad guy here.
Besides, APK seems to have done a pretty good job at showing just how much of a troll you actually are:

Oh and I like the lies you often tell about how you sue people for insane amounts of money for offending you, or how people have to buy full page ads to apologize to you personally. This is yet another trait of narcissism, by the way.
I have never said that I think you would be someone who would be a desirable visitor or immigrant to Canada. That's the voices in your head.
And when I sued for sexual discrimination, I demanded an apology in the newspapers and a $100 donation to charity, not "suing people for insane amounts of money for offending" me. Again, that's the voices in your head. Or you think that a $100 to charity is an insane amount of money. Either way you're below pitiful.
You're such a liar. But then again, everyone already knew that.
"Transparent" is a shit show that trades on every stereotype going. A man in drag is NOT a transsexual.
I have never said that I think you would be someone who would be a desirable visitor or immigrant to Canada.
I didn't say it in that way, however I do like how you use the word "desire". You clearly wanted me to "come" to you, so how is that not desire?
And when I sued for sexual discrimination, I demanded an apology in the newspapers and a $100 donation to charity, not "suing people for insane amounts of money for offending" me.
And where, pray tell, is the proof that you were actually able to enforce such a demand? Show the court record with your name on it showing the judgement forcing the other person to do this, or it didn't happen.
Or you think that a $100 to charity is an insane amount of money. Either way you're below pitiful.
Ahh that's the thing about narcissists, they deny their missteps it til the cows come home, but when the proof comes...

What's worse is you don't even know your own legal code. While I'm not an expert on Canadian law, it seems that nothing you said would apply to me or even a Canadian who happens to be like me: Moral damages that you threatened me with don't even apply to somebody like me and only apply to employers who have wrongfully dismissed you. Besides, in your case it would be easy for an employer to fire you just for being a dick all the time, or maybe they just don't like butt ugly people. At the very least, this is probably why your pay is shit, even though you like to attribute it to you giving yourself the chop.
And then of course, you threatened me with discrimination charges, saying, and I quote, "I'll have the cops on your ass in minutes", only that wouldn't actually happen because it also doesn't apply to somebody like me. You'd call the cops and they'd be like "Son, it's not a crime for somebody to offend you, and we're not in the business of offering a shoulder to cry on." And your earlier comments about people identifying your real gender being a crime doesn't seem to be a crime. And again, while I'm only vaguely familiar with Canadian law, it seems that you're grossly misinterpreting your own country's laws. To wit:
Discrimination is an action or a decision that treats a person or a group negatively for reasons such as their race, age or disability. These reasons are known as grounds of discrimination. Federal employers and service providers, as well as employers and service providers of private companies that are regulated by the federal government, cannot discriminate against individuals for these reasons.
In other words, speech alone does not qualify. This remains true of the C-16 bill that was enacted two months ago. So in reality, Canada isn't as nazist as you want it to be. So me identifying you by your real gender or saying that removing your genitals doesn't make you a woman is not illegal, nor can it gain you any kind of civil damages.
Also as for your statement of winning two cases against somebody: I'm calling BS because you're all talk. Show the court records with your name on them along with the actual judgement amount, or it didn't happen. Like the US, Canada also makes court records public domain, so you can certainly obtain them. Don't be stupid and give some sort of cop-out like "you're not worth my time", because that will only confirm how transparent you are.
When I have an old piece of coax to discard, I often save the shield and throw away the rest. The braided pieces of copper wire make nice RF ground lines.
