1. Topband: Automatic Switching on 80/160 Vertical (score: 1): Author: "Chortek, Robert L" <rlc@berliner.com>; Date: Tue, 1 Mar 2005 14:43:58 -0800; Hello Topbanders, I am trying to design an automatic bandswitching system for a linear loaded vertical I am building. The antenna will be a full 1/4 wave on 80, and will have linear loading for 160.; /archives//html/Topband/2005-03/msg00008.html (8,550 bytes)

Re: Topband: Automatic Switching on 80/160 Vertical (score: 1): Author: "Tom Rauch" <w8ji@contesting.com>; Date: Tue, 1 Mar 2005 20:50:41 -0500; avoid coil Linear loading simply inserts a compensating inductive reactance that cancels the antenna's capacitive reactance. If the antenna is X feet tall and needs Z reactance, you can get it throu; /archives//html/Topband/2005-03/msg00010.html (8,175 bytes)
