W4ETO is looking for one or two 20 ft sections of Tri-Ex T-20 tower. For ETO/ALPHA's club station in Canon City, CO, in '87 we put up 120' of T-20 and a big HyGain LP. But nobody had time to operate.

Still looking for one or two 20' sections of usable TriEx T-20 (guyed) tower. Guess T-20 also came in 10' sections (T-10?) - probably could use two to four of those as an alternative. Will much appre

Divide at Breckenridge, CO. The 80' tower was tightly surrounded by ~55' lodgepole and spruce trees, making "up-and-down" tuning totally impracticable. Designed the yagi with YO, using a gamma match

Jim... Unless I'm missing something, it shouldn't require an expensive vac cap to tune the DE match of a parasitic beam. RF peak voltage across the gamma cap shouldn't normally exceed perhaps a few

Jim & whomever..., Just discovered my conspicuous typo in 1st line of 2nd paragraph: the dual band antenna was, of course, a combination 5 element 20m yagi and 75/80m rotary dipole. Sorry. Dick Ehrho

Here's a practical & realistic consideration I haven't seen mentioned -- but It probably ought to be taken into account when worrying about gain & F/B across the 40m (or 80/75m) band: IMHO not much i

Want to buy or possibly trade gear for * 20 to 40 feet of TriEx T-20 tower in good condition...consider up to 120 feet if price is right * Also ground - or possibly elevated - K0XG or comparable base

Joe N4JBK ... Don't know where the comments you mention about M2 quality came from, but my experience has been different. QTH at W4ETO/W0ID from 1990-2007 was at 10,700 feet elevation on the Continen

Bill, you should drop a line to cqtestk4xs@aol.com . I corresponded with Bill (K4XS/KH7XS) recently. Bill has been using a three-stack of M2 KT36XA's in KH-land and is very happy with them. My last 7
I had an M2 40/30M 4 el linear loaded beam up about 6 years at W0ID - 2 full miles above sea level on the continental divide. Subject to wind, rain, lots and ~25 ft of snow/year. Also had the M2 6el
Charlie: Pete & Bob are absolutely right: you do NOT need a peak-reading wattmeter to tune your Alpha. Thousands have been tuned up just fine (and have survived up to 40 years!) using only the intern
Sure hope that "airplanes" comment was intended as sarcasm or sly humor... They make airplanes (partly) out of structural foam, plastics and rubber, too. EVERYTHING depends on details of the applicat
