May I echo John's comments. I've used a 40 foot Rohn 25 tower with Hazer
here in Alaska for many years - works great. I release two guys to drop
the antenna, then reattach them after it's down just to keep the tower
braced. After working on the antenna, I reverse the process. As John
suggests, I only work on the antenna when there is no wind. No extra
mechanical complexity complexity that I can see. Crank up towers have a
similar winch mechanism and I don't see people "shuddering" over them. The
tower has withstood 125 mph wind gusts and I've never had any problems with it.
