Hi Friends, I am looking for the winch handle for a Tri-Ex THD series crank up tower. Tri-Ex will not answer my e-mail requests for help. If you have one or know where I could find one, or have an id
Hi Tom, et. al., I'm right now debating whether to put my quad back up at 120 feet. It is now at 90 feet. It is used primarily on 20 meters, but once in a while on the other four bands up to 10 meter
They aren't actually at the same location, but about 500 feet down the street. The basic terrain is the same; quite flat.... There are a few differences in the powerlines and fences, but that is abo
Hi, I just acquired a Tri-Ex THD-7122 light duty 122 foot guyed crank up tower. It didn't have any guy wires and so now I'm looking for a good way to guy this tower. It has seven sections and that co

Greetings Friends, What have your experiences been on the difference between 90 feet of height and 120 feet of height on 20 meters? About five years ago I lived about 2 blocks down the street and had
I had a 4 element yagi at 120 feet and noted some rain static. I changed it to a 4 element quad and the rain static went away. Of course the QRN from a local power line was the same. 73, Rob, KL7NA/W
Thanks for the comments Bill. The terrain is flat in both locations to at least 50 wavelengths, with the exception of some buildings. In the west direction about 10 wavelengths away is a long 1 stor

Thanks Phil for the advice. I have two prop pitch rotators I would use if I needed something that would turn the world. I'm in a rather unique situation though. I have a THD-7122 (122 foot light duty
Greetings, It looks like the UV has turned the pliable gray jacket of my 15 year old rotor cable into a brittle hard cracking mess. Can anyone recommend a cable that will last longer, and will remain
Hi All, As Bill (W5WVO) recently put it, "The vast majority of you seem to think the SteppIR yagi is the greatest thing since the discovery of the ionosphere! " At this time, I haven't been able to f
Hi All, It seems that all messages from sometime on April 22 to sometime on April 24 were lost. At least I sent in at least one that didn't make it. I just resent that one. I don't know what might ha
