Man Builds 60-foot Tower to Get Highspeed Access 348

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! "

    I didn't see the protocol (was it wifi?) in the article, but why not ask the church to put a repeater in their tower in exchange for setting up their computer to access the same ISP?

    Another case of over engineering the solution to the problem.

    Buy some used rohn 25 or similar at a ham radio hamfest or swapfest. The tower comes in 10 foot sections and is self supporting to 60 feet. Put half a section in a yard of cement and go up from there. A hinge bracket at the bottom rocks all.

    And if you have more money to spend get a Hazer system [isohunt.com] so you don't have to climb the tower to get your antennas to the top.

    Since this is a digg repeat, I'll tell you what he said. ;) Evidently, he asked them if they could work something out and they said no.

    It is overengineering a bit, but not so much if you actually do have access to the crap he has and the ability to do it.

    um...no.
    those tubes are defintely not six feet long if they're a metre in diameter.
    Six feet is 1.8m - they're definitely not longer than they are wide.

    It is actually entirely possible for those of us using metric to understand the relative sizes of legacy measurement systems.
    Apparently it's not so easy the other way round ;)

    Impressive? Ham radio operators have been doing it for more than 50 years now. NOTHING that he did was new, innovative or interesting in any way. Ham radio operators always knew that you can get free antenna towers by knocking on a door and asking "I'll take down that ugly tower for you for free." Anyone paying for a used old tower is nuts. And everything else he did was plain old silly. He could have easily dont it by cooperation with the owner of the WIFI signal he was trying to steal and a pair of cantennas bouncing it off a house across the street. (Yes flat aluminum sided houses make awesome Wifi reflectors. I did this about 3 years ago for a friend that wanted to share wifi with a friend down the street. 2 primestar dishes and 1 house at the right angle across the street and we had a wifi link.)

    Just because someone finally discovers what Ham Radio operators have known for decades certianly does not warrent front page on slashdot.

    Hey I hacked a "easy" button toy from a popular office supply store to spew profanity as a practical joke at work... can I get a front page story?

    Comcast speed/reliability doesn't even come close... Static IP(s) possible? How about a symmetrical connection?

    I know my [home] wireless connection has been reliable enough to move telco POTS lines over to VoIP. Static IP and proper reverse DNS is very helpful too. The 10Mbit uplink (both up and down stream speeds) absolutely smokes anything I've seen Comcast offer -- or DSL for that matter... Fortunately I sit in one of the highest areas in town with no obstructions to my ISP's antenna's. Otherwise -- I'd be putting up a tower too!

    My ISP doesn't have any issue with me running on a home account using my own [home] domain. I host my own DNS, Email, Web Server, Video-Monitoring, etc. Whatever I want. Of course I'd expect them to want me to go to the "business" account if I was using their connection for profit (I am not) -- otherwise the bottom line is that the browsing data, email data (in and out), etc ... would all be going over their bandwidth. Why piss off the customer and limit them (they do not)?

    Comcast and at&t (SBC) certainly don't offer such options. A symmetrical connection *is* key...

    I'm in a rural part of Ontario with no cable or DSL and several of us in this area have 50 foot towers so we can get high speed access. It's an expensive option, but if nothing else is available, you do what you have to do.

    Good old boys should sometimes stay inside watching tv, then get up and go to the bar.

    The new splash of paint he put on was indeed absolutely mandatory - corrosion Control is a big deal in towers. You must grind off all the rust you can find, and place a good sealing paint meant for this purpose on it, completely cover everything. Use galvanized bolts, and preferably inspect them occasionally. I know its hard at home, but it should be done at least every few years so that you don't end up with a tower section in your living room.

    Lightning rods....Lightning rods don't keep your tower from being hit. In fact they increase the likelyhood of them getting hit as it brings 'the ground' closer to the cloud that is making the big booms. The point of a lighting rod is to provide a path of least resistance for all those lightning strikes so that it goes to ground through the damn rod instead of through your computer equipment.

    Erg. Simpletons.

        I want you slobbering wireless fanboys to listen carefully.

      Used towers are dangerous. You can get stitches and broken bones handling one 10' section of new Rohn 25 if you don't have competent help. A fall from 6' can be fatal, a 'lucky' fall from 20' is still going to leave you with a lifetime of disability. Towers are not a permanent fixture. Even with care they rust and they get metal fatigue if they're not properly braced or guyed. No professional will reuse tower components without a careful visual inspection and most will just say no unless its the smallest cross section segments like Rohn 25 (12" face) and they're not going back up in a large configuration.

        If you get it down and home with all of your toes and fingers intact you've still got to get it erected. A proper base is an art - see a prebankruptcy Rohn catalog for details. You need to calculate the wind load for the size of antenna you'll use and make sure you're using appropriate guying or bracing for the given load.

      The tallest building I've ever had to service was 634'. The tallest facility I've ever had to manage was 485'. The tallest tower I've ever personally climbed was 300'. The tallest I've ever specified myself and helped install was 60'. The tallest water tower I've ever worked was 135'. The most I've done in the last year was an install at 55' on a 185' Penrod 30. The only experience I don't have is dealing with cylindrical cellular type towers.

      Stating my experience should shut down the cantenna artists who just became tower recycling gurus by reading that article twice, but I'm at a loss as to how to say this so that I won't get someone saying "Aren't you special?". I am special in the scheme of Slashdot, because I talk about things I do rather than things I fantasize about doing.

        So much for my resolution to never, ever respond here again.

    Federal law protects the rights of HAMs to have reasonable accomodations (i.e. towers) to do what they do on their property. So long as what you plan to do is reasonable (structurally sound, etc.), you can tell the city, state, or HOA to bugger off.

    IANAL, but that's what I read in QST magazine when I held a HAM license. They even had something you could print out with the applicable regulations and how, being Federal, they trumped any stupid state or local restrictions, including HOA crap.

    we do this on a regular basis for customers with lots of foliage and who are desperate to get broadband. this is actually very common.

    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.

    This guys tower is going to come down the first time it is iced over and the wind blows strong. The weak point of the tower is the welded base plate. The place where the tower meets the ground will have the strongest amount of stress on it. It will be stress pushing in one direction. If he uses guy wires it will be even worse. It will be a twisting motion at the base. As far as I can tell, the site was not slashdot ready, he never used rebar to make a cage for the base. If he never took the tower completely apart there could be other weak points he does not even know about. His story should be a primer of how not to erect a tower.

    I had a 48 foot rohn tower I used for Amateur radio use and it was a tad overloaded. My hole was more of a polygon than a square and besides a very strong rebar cage for the base and the tower legs which were sunk 3 feet into the concrete, I used a little over two yards of concrete. This may sound like overkill but with the tower load I wanted it strong. Good thing. We had some of the strongest pacific storms after that tower went up. It took winds in excess of 100MPH. That wind uprooted orchards in our area and knocked over a few towers. Mine was hardly moving.

    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.

    My father built a tower for a fellow amateur radio enthusiast about 20 years ago. The pivot for the tower was welded onto a thick steel tube (originally for a petrol station sign - way overkill, the wall thickness was around 10mm) with a big steel plate welded to the bottom. 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.

    It's survived 20 years of Scottish winters quite happily. Even some of the original antennas are still flying, despite regular 140mph winds.

    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?

    It sounds like your father did more than this person did. The wind load on the type of tower this person has is quite a lot. The connection to the base is but one thing wrong with it. He used no rebar in the base. He has several different concrete pours instead of just one with no rebar connecting the layers. He has a high water table and he put no gravel in the base for drainage when the table drops.

    I am a ham radio person myself. I know a lot of people in the radio business who do towers for a living. They would cringe in fear on that tower. True, the tower may never come down but I would sure hate it to be aimed at my house in a high wind. I have seen towers that were brought down with winds of only 90MPH and no ice load and erected better than his.

    I hope you are right......if not I hope he is insured.
