Why is this so? Black, by its nature, is a highly absorbing color for visible light of all wavelengths. And depending on the paint, it likely does a commendable job of absorbing in the UV as well. Pe
If the proposed coax entry point is "far" away (say 40 feet around the perimeter of the house) from the utility ground, what's the best thing to do? Mine will be like this - FWIW, the coax will pass
I feel it necessary to say that I DID tie off my coax at each coax arm on my former crank-up (72 footer, 4 sections). It's not rocket science to get it right. Each arm had a small coax loop to allow

Technical answer: It probably won't take very long for the aluminum to get that nice, dull look, and become less visible (without paint) all on its own. Political answer: Painting it a dull color rig

Oops, that's $150 for the COMPLETE set. $60 is for aproximately 6 year's worth. Mea culpa. N2MG -- Start of forwarded message -- Subject: RE: [TowerTalk] finding resonant frequency of a shunt-fed tow
Is there a good way to uncoil CATV (or other) hardline in a manner that will produce a relatively straight, un-kinked and bump-free line? I can imagine "simply" uncoiling it slowly along the ground i
<< First, they use a flat bottom plate on the concrete. I doubt that these rotate at all to relieve the moment at the bottom.>> "The wide footprint on the pier may allow the tower to rotate about the
Part of a recent thread referred to wanting the ability to change a guyed tower's height at some date after initial construction. While a noble goal to plan ahead, I wonder what kind of added stress
I read here often that folks recommend that rebar be kept "inside" the concrete (and by several inches) - away from the nasty, wet soil in an effort to protect it from rust. My situation (high water
Anodizing is unfortunately non-conductive. Some other anti-corrosive treatments for aluminum retain conductivity such as iridite/alodine. If I recall, these aren't as durable. Some details: http://ww
A topic currently near to my heart (and wallet). I'd like to see the numbers for your 75 foot R45 tower. For a tower of ~120 feet (for which I'm in the throes of constructing) the numbers show that P

While we're on the topic of hardware - is there a decent source for Rohn-like galvanized hardware other than Rohn itself? I'd especially like to get my hands on some of the galvanized U-bolts that ar
Steve, you are "half" right. The lift effort is part of the overall load on the ginpole (everyone forgets this), so without any mechanical advantage there is 2X load weight applied to the ginpole. If
Nothing "magical" about it... http://www.howstuffworks.com/pulley.htm has some good graphics although no description of the force on the fixed pulley (our ginpole), so one needs to sum up all the "do
Why is this NOT how a gin pole is configured? Even if one ties the fixed end of the rope to the tower (say when lifting a beam or rotator that need not rise above the tower top), one has not material
