Re:Omni antenna questionI'm curious how much noise and interference you expect they'll get since they're up in the mountains and remote? Well, see that's the thing. I didn't know that. And it's true that you'll probably have less noise and/or interference way out in a remote location, but you can never be sure. It's tripped people up in the past, believe me. They need about 170deg of horizontal beamwidth and 30deg vertical So use two 90 degree ( 90 deg horizontal, 30 deg vertial ) sectors. Or even the 180 degree ( 180 deg horizontal, 10 deg vertical ).

WiFi and WiMax serve different needs-Beauty Mark.
"Those folks would be willing to put up with the expense/uglyness/non-portability of a dish."
And a DirectTV dish is attractive?

Hopefully you pick girlfriends better than you do dishes.

Re:Friends of SCO
Sh-ya! Utah is the spot. I just bought a high gain wireless antenna from this place: http://www.pacwireless.com/
...right down the street. We almost had the Utopia (municipal fiber-to-the-home), but missed it, Lindon might still get it though. Ski Utah! Whoot! Mid-west side! Novell power! yada yada...

vs commercial antennas
As cool as this antenna is, it isn't very expensive to buy a nice prebuilt wireless antenna these days. Pacific Wireless dishes, for example, are about US$50 for 19dBi or $70 for 24dBi. I've used their products, and they are very nice. I've given up on building 802.11 antennas: it's too much work vs the cheap commercial antennas for me.

Impressive, but anyone could do the same for cheap
From looking at the pictures, they just used a parabolic dish antenna. You will get about 20-24db gain on one of those and it narrows the beam a LOT for that gain. So dont think anyone within 110km can log onto the network and lan away. This is a strictly point to point thing.
Ive got two c-band dishes right now with a point to point network around town. The longest link is around 30km. if i dindt live in the mountains(of if i wanted to hike to the top of said mountains) i could get a link as far as the curvature of the earth allowed me. Two ten foot dishes with 30-35 dB of gain is capable of amazing things at 2.4ghz.
OH, and about legality. 500mW will be legal anywhere. But with a dish gain of 24dB, they will have a equivelent power of around 128 watts. DEFINATLY illegal, at least here in canada.
If anyone is interested in playing wiht this and they dont have a lot of cash, there are lower cost ways to do it.
You can take any parabolic dish, which can be had for about 50 dollars, and use a cantenna as a feedhorn. Or if you wanna spend 20bux more, just go to Pacific Wireless and they sell a 2.4ghz dish and feedhorn, with 24dB of gain, for 70bux. even comes with the pigtail.
For a cheap amp, you can buy 1 watt 2.4ghz amp IC's for very cheap. Here is a site that has a schematic and board layout for it.
With a watt and a 24dB gain antenna, you have an ERP of about 256 watts.
Have fun! -

Making your own dish might be fun but..
There are much better solutions. While a pringles can and cantenna might work, assumng you put it right in the focal point, build the cantenna right, and can find the dish, this might be a better way to go:
Try this.
Its a 24dB gain antenna (Thats 256 times power folks), its guaranteed to work, it HAS a feedhorn, and all the calculations have been done for you. Not only that, its a grid antenna so there is almost no wind loading. You might pay 50bux or more for a primestar dish on ebay, plus trying to get the can into the focal point, etc. There is certainly a certain apeal in doing it yourself, but sometimes work for the sake of work is no fun at all.
The best thing? Its only 70 bux, WITH the feedhorn and pigtail.
Right now im using one of those, and two 10 foot C-band dishes to make a big triangle network connection. The C-band to C-band dish connection is over 30km long. (Yea I'm in Canada: 30 kilometers = 18.6411358 miles)
