Hi Guys, I got a few emails asking where I got the insulated base. I made it. The insulated legs on the market are pretty expensive, and I didn't like that they are in tension and compression when th

I must be a heretic on tower building. If I were an engineer, I'd probably still be designing my first tower. I can see stress tensioning the guys on a 600' commercial tower, anyone can, but on 50' o

Anecdote is a single occurrence. 15 is approaching empirical evidence. I just think the engineers and lawyers at Rohn went to the utmost lengths to protect their own buts. I would too if I owned the

The Log gain is more like a 3 el yagi, I haven't used a Mosley or M2 log periodic, so I'm not familiar with their weights, but the T-8 log was very easy to lift to the top of the tower when compared
