That product was absurdly expensive. I suggest instead you look at 3/4" or 1" copper tubing. A few feet is just a few dollars, and you can run any sort of tapping screws into it you want.
I've said this before on towertalk, but it seems to me that one tradeoff might be to permit a setback smaller than the guyed tower height IF the guying scheme uses more than one guy anchor per direct
Trees are "grandfathered". Like structures, if they were there before the zoning laws were put in, they get to stay ;^} 73, Pete N4ZR Check out the World HF Contest Station Database at www.pvrc.org
Rohn isn't necessarily the last word on guy grips, of course, not like PLP. However, I was told (with straight face, I think), that water sliding down guy wires and freezing inside the ends of guy g
I think this spacing may turn out to be too close, particularly between the A3WS and the TH-7. I think this is asking a bit too much of the Ham IV. A Tailtwister would be a stronger choice. Wouldn't
Glenn, I would not hesitate. My Yaesus have been bullet-proof. I have a G-1000SDX turning a C-3E and a 2-el shorty forty, and a G-800SA turning another C-3E on a sidemount. The only issue in 5 years
The subject line almost says it all. This question originated because a friend and I were speculating about replacing the linear loading on a Force 12 EF-240S with lumped inductance, placed at the sa
Steve and I have agreed to disagree on the need for additional rivets. I have not had anything even approaching an element rivet failure in 5 years with 3 force12 antennas. In my limited experience,
Judging by the schematic in the new G-800SA manual, they totally changed it, and reduced the part count by about 2/3, which has to be a step forward in reliability. It works differently now -- for ex
ARRL invited manufacturers to include gain and pattern claims in their ads, if they would supply NEC-4 modeling data to substantiate them. Nobody did. 73, Pete N4ZR Check out the World HF Contest Sta
Tom Frenaye points out that M2 did submit modeling data for some of their antennas, and were allowed to run gain figures in their ads. He's right, and I apologize for being over-categorical. I found
I don't recall that. I was advised that 1/4 wave was minimal and reported anecdotally that when I went from 21 feet of nonconductive guy to my entire top guy being Philly, my 40m yagi on top seemed t
I think it's the "sliding" part that is fooling you. The classic fence post driver is a steel tube about 2 feet long with handles near the top end and a plate plug welded inside that end. It's quite
Maybe I'm being over-optimistic, but it seems to me that the strong trend in state legislatures toward adding PRB-1 type "reasonable accommodation" language to state codes, plus the precedent of the
Has this thread maybe, just maybe, run past the point of diminishing returns? 73, Pete N4ZR Check out the World HF Contest Station Database at www.pvrc.org
Well, Jefferson County, West Virginia's Planning and Zoning Commission has formally categorized amateur radio towers and antennas as Essential Utility Equipment, thereby exempting them from regulatio
I just modeled a 3.5 WL wire 1/2 WL above ground, fed in the center, at each end, and at 25 percent of the length from one end. The patterns are almost the same, regardless of the feedpoint location.
Another option worth considering is the local farm supply store, like Southern States. They have galvanized hardware priced *by the pound* (literally), cotter pins, etc. Not the place for buying Grad
I was glad to see K4IA's message, which added some useful perspective to a pretty light-weight thread, but this last paragraph kind of threw me. I don't think anyone should have been surprised that t
I think K1MK may have been closest to the mark with the mention of St. Elmo's Fire. I found the following explanation on the Scientific American web site. Elsewhere, I think I have also read that it
