I have moved my Tristao (predecessor to US Towers) many times. The Calif PE opinion on the tower sections may be accepted, but many areas was a local PE to certify the base design and installation fo

What the Inspector chooses to look at, and in what detail, is at HIS discretion. I suspect he drove by several times, perhaps looked in the hole for the base, perhaps looked at the rebar, and looked
Might I suggest, for those with big loads on the Rohn tower with holes pre drilled. Rather than put a bolt in the hole in the air. Before you install the tower, plug weld the holes. You can re galvan
If one leg is "rusted clear through" the whole tower is probably rotten with rust from the inside. I would have a crane remove the antennas if they are worth it, and the rotor, and junk the tower. Ne
Well, I have used TV antenna rotors, including the big ones like HAM-M, T2X. I have used PropPitch. I have used, and still use the TelRex 2140RISX. I have also installed 4 or 5 garage door openers, s
Why would "110V on a tower" be a no no????? Wilson rotors have a 110V motor, all TelRex rotors have a 110V motor (likely more if overseas), I think the old EF Johnson rotor (1940-50 era) had a 110V m
Finally someone asked the right question. You keep the lightning outside the station. You don't go off the air. You don't hide under a tree. You don't play golf in a thunderstorm. But you have two ef
I think every post should be taken with a grain of salt. I probably should not even respond to a post that starts off "I'm not an engineer...I dropped out of ME... but "common sense".....etc." But I
Well, I dunno. Lightning is only electricity. Static electricity for sure, but only electricity. It really does follow Ohm's law just like a AA battery type electricity. You certainly CAN create the

The original question was not how to take down Rohn 25, the question was about an old tower or a roof with unknown guy problems, unknown roof support, and unknown internal corrosion in the tower. If

Thanks Frank. I presume that this change is only of interest to those with GUYED towers? I can see no reason to change from #4 solid copper wire, or copper strap to copper clad steel ground rods if
During my 31+ years in the Navy, most of it in nuclear submarines, I've certainly seen my share of bimetallic corrosion. However, when the steel tower is above ground on a 40 ton concrete pad, and t
Sounds like an intelligent decision to me. I don't like to climb in wind. If the tower is sound, and the mast is correctly mounted in the tower, and the steps are strong, it's no big deal at all. I h

Does anyone know how to get in touch with C. Ercolino? Young Charlie was already running TelRex (or running it down) when I purchased my last 2140RISX rotor from TelRex. I need some replacement parts
