1. Topband: 160m Ant on 80m? (score: 1): Author: "Thomas Hoeppe" <thomas.hoeppe@asamnet.de>; Date: Fri, 16 Apr 2004 07:15:26 +0200; Hello, has anyone tried to use a 160m Vertical on 80m? The antenna is mechanical 33m high, electrical about 37m (Top-coil). So it will be nearly 1/2 lamda on 80m, and I want to feed it by a parallel-; /archives//html/Topband/2004-04/msg00112.html (6,623 bytes)

(score: 1): Author: David Gilbert <rimradio@direcway.com>; Date: Fri, 16 Apr 2004 08:48:51 -0700; Tom, I believe your antenna should simply look like a vertical halfwave dipole, except electrically off-balanced by the coil at the top end. In theory, any simple vertical one half wavelength or less; /archives//html/Topband/2004-04/msg00115.html (9,649 bytes)

Works perfectly.

It would all depend on what it looks like on 80, and that would depend on how much L the an; /archives//html/Topband/2004-04/msg00121.html (8,532 bytes)

I played around with different loading coils in the simple EZNEC model I created and the base impedance swings all over the place, both real and imaginary components.
