Thought of one more thing. Are you sure the tips of the elements are 3/8? Or are they 7/16? HyGain has long used 7/16 for element tips combined with their swaging methods. Just a thought. Ken K6MR Ba

The only HS tower Ive ever seen in the wild was owned by W6YI back when he was WA6EKL (late 1960s). Could have been a HS-354 or a 471. As I remember the whole line of TriEx guyed towers, they made a

I use three loops, and have the rotator set at the loops tightest point (depends on which way you wrap the loops) when installing. The loops change size very little when rotating so no risk of snaggi

Theres no magic or guessing necessary. Get the software that calculates the forces on the mast and tower and make sure you dont exceed the rated capability. Towers are rated for so many square feet i

Sounds like an excellent modification. My question is what failed in the prop motor? Did something actually break? The material in a prop motor is exceptionally strong, and I cant imagine any kind of

We always found the spline/sockets at wrecking yards. At least at that time there wasnt much call for them and the one yard we used always had a good supply. And the exact model isnt critical as long

Climbing a W braced crank up (Tri-ex/Tashian) is no different than any of the W braced fixed towers like T-15/T-20/T-26. Weird yes, but with climbing boots its not a problem. Just put some big pipes

Thats the original HyGain RotoBrake controller. A little tough to interface directly to anything else because it uses a 400 cycle selsyn with a 5:1 gear train. Very nice display though. Of course now

How do you get a beta match to work on all bands ? Hygain also does it on the TH7, so the secret must be out. Ken K6MR Meanwhile, Mosely is still blathering on about... establishing 52 ohm resonance.

Even the original TH6 with the single driven element had the beta match. I think the TH3 did also. That must have been a bunch of trial and error since the TH6 has been around since the 1960s and I t
