I've tried to contact Tom at Force 12 about this, several times on e-mail and once by phone since October 14, and have gotten one e-mail in return from Tom that said that they have had some server pr

Here is my report on rust: About half of the length of u bolts etc that are plated and not stainless on Cushcraft were rusted but not to point of nut will absolutely not come off. Spots of rust, but
Good afternoon. Contrary to what you think, I have sent you an e-mail response. Actually, twice. Was wondering why we had not received a response. Interestingly enough, I sent an e-mail last night an

Good afternoon, Steve. Need to make a correction on your longevity statement and I hope everyone who read it also reads this one! The 3 year statement is quite incorrect. Antennas using the current F

I'm not Tom, so all I can offer is one data point. I just took delivery of my new Orion OR-2800 rotor. This is the strongest rotor this side of a prop pitch. It is a worm drive, weighs a ton and is b

I've been using small (1/4" or 3/8") poly rope in every element I install for years; it definitely works to STOP flutter, the major cause of element failure in otherwise sound mechanical designs. Tel
I think you are probably right, Steve. My only experience with poly rope in elements was with a stack of Wilson monobanders many years ago. In addition to the poly rope, Wilson used soft plastic end
You didn't ask me but... You're correct. I don't ever remember seeing "amateur" hardware (hoseclamps specifically) on any commercial antenna. The commercial manufacturers also typically don't have th
