I'd get it as close to the tower as possible, thus decreasing the moment arm leverage on the tower. There was an article in a recent CQ by Dick Weber, K5IU, on this very topic. Don't forget that 100
I've never seen one, not even in the commercial field. Everyone picks up their knowledge on-the-job and/or from more experienced hands. This is where the splendid folk on TowerTalk can be real helpfu
Hello, all -- I don't normally cross-post things but this one is of interest to all of us who are interested in antennas and their competitive performance. Cheers, Steve K7LXC I still have a few call

Good question. The best info I've seen on this is in Dr. Dave Leeson's (W6NL, ex-W6QHS) book "Physical Design of Yagi Antennas". It's out-of-print but you might be able to find a copy. Here's a littl
Thickness doesn't have anything to do with the specified yield strength of the material. The thickness has more to do with resisting the bending moment of the mast. (I'm not an engineer so excuse me
