I have seen some that are pre-bent on a military type tower. Probably to keep the turnbuckles centered and prevent rubbing against the sector plate. Mike, W1NR There is a 200 ft heavy duty guyed Flor

You can never guarantee a tower will not fall less than %100 of it's height. The only basic restrictions here in Marlborough, MA for Amateur towers are that it conforms to Mass. state building code (

You don't mention your mast size or wall thickness. With 2" O.D. 1/4" wall at 70MPH, I calculate ~20,000 PSI yield strength required. For 1/8" wall I get ~32,500. At 90MPH the requirements go to ~32,

This is what I meant. You can fit a T2X inside a 25G section, but only if you have some other access other than through the braces. I tried for over an hour to get a T2X 7' below the top of a 120' to

In most cases, you must have undisturbed soil. Rohn guy anchors are an example where you need undisturbed soil on the bottom and all sides. Rohn short bases need a gravel bed underneath them for drai

The best solution is to install weatherproof limit switches on the tower that actuate just before the arm contacts the tower. This way, you don't have to worry about mast slippage which would make th

Does anyone have any REAL data or experience with mounting a 15M beam 10' above a 40M beam? The concensus is that 15 and 40 interact too much. But all I have heard is opinion and conjecture. I know s

Baseboard heaters usually have no neutral and the ground that is there is not of sufficient size to handle being a neutral too so converting to 2 110V lines is out of the question. However, most base

I have to disagree. If the tower, antenna, mast, etc. is properly grounded, lightning should be diverted to the ground point at the antenna. Grounding the coax helps relieve any residual. Although a
