It seems only one responder stated a tiltover arrangement would allow antenna maintenance/repair without having to climb it or rent a bucket truck. A winch + pulley setup is used to haul it up/down.

The current recommendations for terminating EHS steel guys are the Preformed Products Big Grips, BG2142 for 3/16EHS and BG2144 for 1/4EHS. They have superior holding strength and take far less time t

I read the book Steve recommends, and purchased a new-to-me Force12 C-4XL (40/20/15/10m) yagi for a very good price. Force12 says it works on 17 & 12m using an ATU. My TS850SAT likes it on 17m w/o t

Hi John, This is very helpful. How does fiberglass age in such environments? Would that be an option? Also, did you try to do anything with the palm trees? Verticals, wire beams, etc.? Rudy N2WQ Sent

According to N6BV, who knows his stuff... Beyond approximately14000 feet has very little effect on the TOA for HF. Close in is far more important. You can test this by making up a file with hypotheti

In the past N6BV has been kind enough to supply me the "numbers" for my QTH using his wizardry to generate them in a few minutes and then ship me the files. His files went up to about 14000 feet, and
