1. Topband: Feeding 160M Vertical on 80M (score: 1): Author: Bob K6ZZ <bob.selbrede@gmail.com>; Date: Mon, 6 Jan 2014 19:18:47 -0800; Folks, I have a 60' tall top loaded vertical for 160M and would like to know how best to feed it to use it on 80M as well. On 80M there will be some pretty high voltages at the feedpoint. Other than; /archives//html/Topband/2014-01/msg00046.html (7,066 bytes)

For several years I ran a vertical 40m 1/2 wave that I fed at the bottom through a 1/4 wave of 450 ohm ladder line. Perfec; /archives//html/Topband/2014-01/msg00048.html (10,084 bytes)

Modeling shows that adding a lot of half-wave radials under a half wave antenna increases signal strength by 0.5 - 1.5 dB at low angles, roughly; /archives//html/Topband/2014-01/msg00049.html (8,164 bytes)

At the time I was living in q small duplex on a corner lot and running a bunch of on-ground radials wasn't an option. Still I was working YBs and DUs; /archives//html/Topband/2014-01/msg00050.html (9,587 bytes)

Because something resonates on 160 m with something on the top doesn't mean it will act like a half wave on 80.
