Man Builds 60-foot Tower to Get Highspeed Access

Matt Russell writes "A church was blocking the only high speed signal in town, so he decided he needed to go higher. This is the story of one man's quest to build a 60-foot reception tower in his yard and retire his modem once and for all." From the article: "Well, if you want to have a tower, you need to find one. Buying a new tower is not a good idea, since there are plenty of used ones. In my case, I was in need of a tower that was at least 50', which would cost around $1,000 USD for a new one. The way I searched was pretty simple. I spread the word around town that I was looking for one, and I drove around to see if there was a house with an old TV tower or something like that. If a 30' tower would be enough for you, go to a small town and look for TV tower. If you find one that looks to be in good shape, just go knock on the door and ask if you can buy it. At least 90% of people don't use them anymore, so it's a good place to start! "

The foundation was cast with ragbolts to bolt the tower to, then more concrete was poured in on top putting the mounting plate in the middle of a couple of cubic metres of concrete.

    we found that it's cheaper and safer to have someone (e.g your power company) plant a wooden pole. we've had customers that buried a 60 ft (and a couple of times 70-ft) wooden pole 10 feet in the ground, with some concrete around it, and they've never moved since. you can get a set of pegs to do about 3-4 poles for around 90 bucks, with a tool to drive them in. it helps if you know what you're doing and have some climbing experience, of course.

    we also have a couple of customers that have guyed and non-guyed masts and tri-poles up to 70 ft.... people will do strange shit for high speed porn.

    the worst part is having to do routine maintenance and realignments, just cause it's time consuming and wears you out.

    another neat tower design is the kind that "breaks over" close to the ground, and has a counterweight. you can fold it over, install your gear, and straighten it back up.

    There's a lot of damaging superstitions about lightning. If you're in a lightning-prone part of the country, try to get your information from someone who knows physics and electrical engineering. Your recommended solution should include a ground *field* surrounding the tower, low-inductance connections, attention to take-off angles, arrestors before the wiring goes into the house, and a fanatical campaign to eliminate potential ground loops. You know how you're supposed to keep your feet together if you're caught in the open during a lightning storm? If you have equipment grounded in different places, that's the same as moving your feet apart. Strke current trying to fight its way through sorta-conductive dirt may discover that your equipment is a shortcut.

    You can manage a direct strike: operators of really tall towers get hundreds per year. But it requires a lot of attention to detail and a complete understand of the physics. For an application like this I'd suggest a disposable AP at the tower and no wiring going into the house.

    When I needed a tower for my 40-meter 4 element beam, I managed to search around local hamfests and other classifieds. I ran across a guy who was moving and wanted to just give away his 140-foot tower. Used towers are INCREDIBLY cheap due to the high costs of removal and transportation. If you are flexible, willing to rent a vehicle that can haul one, and expend the effort, you can get a tower for free almost any time.

    Erecting a tower is serious business. You have to know what you are doing, and know it well. It's not a simple matter of throwing it up and climbing it. You WILL kill yourself if you do not know what you are doing. You MUST have your tower installation inspected, and in many cases, you must get a building permit to put one up and have a civil engineer sign off on your pad and guy wire plan. You must also have a registered PE inspect and/or tension your guy wires if you are to be able to obtain liability insurance on your tower. If you do not do these things, and something happens, YOU ARE SCREWED. Towers are heavy, fragile, and wimpy. If your tower falls and kills someone, you're looking at a manslaughter charge unless you can demonstrate due diligence.

    Do you remember kindergarten physics? Remember the machine called the lever? A 60-foot lever has a tremendous mechanical advantage. 20lbs of wind force at the top has 1200 lb-ft of torque at the bottom unless you are guyed properly. It's not uncommon to see wind forces of 100lbs or more during severe storms.

    Putting up a tower is no joke.

    Erecting towers isn't all that hard, hell I've put up 40 foot towers by myself. and I've put up 100 foot towers with 12 element,40 foot boom antennas attached to them with less than 5 people. We never had any cranes or 14 thousand pounds of concrete either. A couple pizzas is all we wanted. I even painted the very same 100 foot tower 10 years later with nothing more than a tower belt and a two by four to slide in between the rungs to hold the paint can.

    But I will admit, you do need a quality tower if you are going over 100 feet. a wide base is very important. Alot of the older commercial towers were the same size from top to bottom, especially the ones over 500 feet tall. and they relied on guy wires for most of their support. Imagine climbing up a 500 foot tower? I don't think I would want to go that high, 100 foot is scary enough.

    Anyone remember this story about one of the tallest structures in the united states falling down and killing two? http://www.eham.net/articles/4033

    Of course, it was a 1,965 Foot Tower in Nebraska.

    The 1,965' tower fall was at KDUH in outstate Nebraska, about 400 miles west of me. As I recall the guys had been improperly tensioned for an HDTV antenna placement. The climbers were about a quarter mile above the ground when it all let go. One of them was 25 and his 18 year old girlfriend was on the ground near the base and had to simultaneously run for her life and watch her boyfriend die.

        KDUH. Almost seems like an Encyclopedia Dramatica article, doesn't it?

      Less famous is the second event in Nebraska that year - an injury to one of two climbers putting up a 'gate' - one of those triangular stand offs for antenna spacing. The gate caught during the lift phase, it was 'loaded' and stuck against the tower, and the guy who broke it free was rewarded with a nice, solid hit that shattered his right arm. Mmmm climbing one handed in agony ... my idea of a good day at work. This wasn't the final blow that put Media Integrators out of business but it did put them out of the tower construction game.

        Not long after that a skillful bulldozer operator in Glenwood, Iowa, half an hour south east of Omaha scored a confirmed kill, hitting the top guy wire for the 300' city/county tower, neatly snapping it in the middle. Most of the equipment on it survived the folding, then was destroyed when they cut it and let it fall; cranes cost and there were safety concerns - easy to load a guy with a tow vehicle and torch the base.

      Not long after that one of the 1,200' towers at Crown Point in Omaha came down during the night. Amazing it didn't damage any of the other three when it fell. The replacement is up and its quite strange to see three properly painted red and white towers and one new galvanized one.

      We've got a bit of a pool going here - will the next fall be the 80' Rohn 25 half a mile east of the I-80/I-480 interchange that is so corroded one of its legs has a inch and a half air gap between tower leg and base, or will we see the badly overloaded Metro Transit Authority tower directly south of that interchange come down with two inexperience climbers on it?
