Hello All I am trying to solve a guy wire problem - they seems to be detuning my C31XR. Last year when I installed the antenna I found I could not get the swr down to the spec level on 15 and 20. Nat

Hi Sylvan, there is a graphic about this in the ARRL antenna book. The theory is easy: stay away from wire lengths that are even multiples of lambda/2 for the frequencies you are using. If the wires

There are 2 things at work - the antenna and the guy wires. First, you need to see if it's a guy problem by keying the radio into the antenna and then turn it while you watch the swr. If the swr vari

Steve, I think that's too simple. If the SWR doesn't change when it turns, it MAY not be a guy wire problem, but you can't be sure because not all destructive interaction affects SWR,and the placemen

Rotating the beam does not always show much of a change. If all three guy wires are equally rf ugly, there may be no change at all. There are always at least two coupled no matter which way beam is t
