Elevated radials. I know all the science is good (I am an engineer after all) but what I found easiest to do when I constructed my 160m inverted-L was to attach a 500' spool of wire to the base and r

The rule of thumb is ½ the wavelength of the highest freq. band so about 9.5 would keep the HF antenna out of the capture area of the 6m beam but of course the opposite would not be true. The 6m beam

Neal, I remember a VNA review in QST some time ago. I am sure you can find it. Meanwhile I feel that you need 2 devices, one for the field and one for the shack/lab. They need to cover the bands you

Youre lucky to be able to string so many radials on the ground. I happen to use a single, tuned, raised counterpoise wire and my inverted-L works just fine. I wonder if anyone has compared the differ
