1. Topband: Dumb radial question (score: 1): Author: "Vanderydt Theo" <ON4ATW@skynet.be>; Date: Wed, 25 Oct 2006 18:33:15 +0200; Hello TopBanders, I have a (probable) dumb question about my radial system. This summer i got rid of my inverted L antenna and put up a shunt fed ,toploaded, tower to use on 160. Not having time to l; /archives//html/Topband/2006-10/msg00169.html (7,393 bytes)

The shunt wire itself is a transmission line. This is what often messes people up when they try to phase shunt-fed antennas. 2.)
