Tashjian Towers makes and sells the LM-470 now. They have a web site and they advertise in QST. de Paul, W8AEF _______________________________________________ See: http://www.mscomputer.com for "Self
For a better check on antenna SWR with the antenna located near the ground - point it straight up with the reflector above the ground. A yagi pretty much ignores everything in back of the reflector.
Or, if you are not going to install a 20 foot mast on the rotator just letting the antenna be slightly out-of-plumb won't hurt. Esthetics aside, it won't make any difference to the rf. I tinkered wit
I was interested in CC&R's in Arizona several years ago and I found that state law required them to be enforced by an HOA. No HOA, no CC&R enforcement. And selective inforcement was not legal. That i
We have one of those darned McMansions in our neighborhood. The neighbors circulated a petition against it so the owners (4 families) erected a 6 foot wall around it. We decided the wall was sufficie
I built a remote antenna relay box 9 years ago using Radio Shack DPDT relays with contacts rated at 10 amps (I paralled the contacts). Works fine and running full power. Drove the 2KD-3 at 150 watts
Arizona state law requires CC&R's to be provided at closing. Doesn't always happen but that is the law. And it is the opinion of at least one real estate attorney in Arizona that if you don't like th
This thread contains a lot of speculation and very little substance. I have always guyed towers - self supporting or not, and have never lost one. Has anyone ever lost a self supporting tower because
My WARC-7 is on a tower by itself so can't help on the stacking, but -- My WARC-7 had no front to back on 30m. A long story but I wound up moving the shorting wires on the reflector out 8" from the F
I use a Force 12 balun on mine. de Paul, W8AEF _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers", "Wireless Weather Stations", and lot's more
While at XZ0A I worked several hams in Phoenix on 40m, the loudest was using a Pro-67 at 72 feet. And all the Phoenix hams were running similar power. de Paul, W8AEF _________________________________
My WARC-7 worked fine on 12 & 17, however on 30 it had no front to back. By placing a known signal source about 100 feet away from it and observing for f/b, I found it was best at 9.5 MHz. Moved the
I like to install my truss support on the boom, near the mast clamp. This way my trusses are already in place and when the antenna goes on the tower I only have to worry about the boom to mast connec
tape No. I actually install a piece of aluminum angle about 3 feet long on the boom, near the boom to mast clamp. One end clamped to the boom and the other end pointing straight up with 2 eyebolts at
I don't think this is true with voice. Let the contesters log in on this one for voice vs cw rates. And for traffic handling where accurracy is critical cw will win every time. de Paul, W8AEF _______
Thanks for the heads up Ed. It just happens I have both of the thrust bearings he is looking for. If he does contact me I will wait until his funds have cleared my bank before shipping. Just in case
I purchased a manual package from Tashian Towers for my LM-470 when I was going through the permit process. It included two D size blue prints that would be tough to reduce to 8 1/2" x 11". The cost
You have leverages to consider that will complicate matters. If your winch is mounted 30 feet higher than the swivel point and the 150 pound antenna/rotor is 120 feet from the swivel point the winch

And please don't forget that elevated radials will be resonant. Gotta be cut to your desired operating frequency or they will really upset the tuning of the vertical. I would expect that at least a p
