Latest in my series of questions, which you guys have been extremely helpful in answering: Is there any reason to go to the trouble of putting a "stub" of guy wire at the top with an insulator on it,
Jerry, Take a look at the tradeoff analysis I have on my Website, specifically, the break-up insulator, Phillistran, and fiberglass rod implementations. I chose the fiberglass rod implementation in p
Guy Insulator Placement de N4KG (Feb 2000) The following lengths between insulators have resonances between the conventional bands (which places their resonancesin the WARC bands :-) - 27, 40, 58, an
That is not necessarily where the problem is. The guy wire can be resonant with the electrical length of the tower at the attachment point, and not even involve another guy wire. When you attach a g
The posts below show the questions that still exist on the need of breaking up guy wires. N7WA got it right. Some time ago I gave info on TT of Eznec patterns I ran of different length guy wires belo
<snip> <snip> In some cases, K7GCO is right on the mark. However depending on the installation, there are valid reasons (not "band aids") to use nonconductive guy wires (or EHS broken up with insulat

Ken blends a number of things together in his post. Let's separate them out: Proportions are at issue. Most of the time I have seen a tribander and a two meter 10 element or some such up together, th
What Guy is saying is: There is a million ways to do it wrong and shoot yourself in the foot. There are only a few ways to do it right. Absent any concrete data or analysis proving you've done it rig

Some mention has been made of using SWR changes to look for interaction. By the time you see the slightest SWR change, you could have totally "cooked" the antenna's pattern. As ZS6EZ pointed out, it
This is a sharp answer with some good humor to a lot of unnecessary nit picking that goes on, on Tower Talk. They never ever contribute any useful info themselves--it's too risky. Any comments. K7GCO
