I have been using neoprene rubber pads between the cast aluminum jaws of my Yaesu 1000SDX rotator and a 20 ft x 0.25 mast on my TX 472 crankup tower. This accomodates moderate misalignment between ma
There are indeed Heliax types w both spiral and non spiral ridges. I have owned both and have tried to put the non spiral connectors onto the spiral stuff. It was several years ago but my recollectio
I have recently moved to pacific nw(Spokane) from sunny south (Dallas). In Dallas I buried lots of Andrews hardline at shallow depths (6-12 inches) with no ill effects over a 13 year period. Up here
Tom: I have read that grounded elements in a monoband beam are OK, however, on other frequencies, the connected boom/element system can have unwanted resonances. That is supposedly why multiband beam
Dave: I believe that the proper way to park your beam is with the boom end pointing into the wind. Most beams are mounted to the mast at the center of gravity (balance point). Since the reflector is
Bob: I have some steps which can be bolted to the mast to clmb it. They are made of 6 inch wide aluminum channel with 2 muffler clamps on each. I even installed a bolt on each end of the top surface
Wes: an abrasive cutoff wheel will do the job. I have a small portable right angle grinder with such a wheel. It will cut welds, angle and pipe with ease. I couldn't get along without it. Mine is a M
When you say "braze", Tony, do you mean soldered as in domestic water systems or something else? 73, Dan, N5AR Not if it is done properly... when properly brazed, it's a sweat joint with a much highe
piece. Does it use a spinning magnet and reed switch for pulse generation as in the OR2800? Tnx, Dan, N5AR Weather Stations", and lot's more. Call Toll Free, 1-800-333-9041 with any questions and ask
Joe, the cable from the winch goes up over the top of the pulley mounted on the vertical post. Then, horizontally to the top of a pulley mounted on the tower leg, out the bottom of that to the vertic

Hi Ron: The extreme variations in signal strength with your different configurations are difficult to explain and might be due to one of the following. 1. Large variations in SWR cause your transceiv
Doug, I owned the 100 ft version of the same tower. I moved it 3 times over a period of 30 yrs while I had it. In each case I assembled it or dismantled it with me on the tower and one ground helper.
Hi Don: I solved a similar problem here when tuning K7OX 160m vertical. He is very close to strong BC stations and the MFJ filter for the 259 did not solve the problem. I used my old MFJ 202 noise br
Jim: I assume you are talking about a KT34 beam sitting on saw horses in a horizontal position. Any measurements made in this position are highly suspect due to coupling to the nearby ground. I have
I use my Iwatsu SS5711 4 ch. 100mhz scope for tuning the 4 sqr antennas I have built. I have 4 equal length coaxes carrying the signal from current xfmrs at the tower bases to the scope amp inputs. A
I have recently obtained a 6 el 6m yagi and would like to find information on it. It may be a Hy Gain unit. The boom is 24 1/2 feet long and 2 inches OD.. The boom to mast bracket is stamped out of s
It was 73 mag nov/dec 75. This question has come up before and I offered to make copies for a buck to cover copy cost if I receive an SASE. One guy kinda forgot the buck and I sent his anyhow but I w
It has been bro;ught to my attention that the article is probably copyrighted so maybe not a good idea to put it on a web page. I am willing to do the copy and mail thing again if anyone needs a copy
Don, I have replaced the cables on my TX472 with the tower in the vertical position and without removing the antennas. I also replaced the bearings in the pulleys while I was at it. I use an extensio
