Hey Paul If one were to put a programmed PIC and some latching-relays together, one could switch that ladder network from inside the shack! :^] Wouldn't that be cool!! Duane
From: "Paul Christensen" IMO, construction of open-feeder line is worth the effort. I am using an old stash of E.F. Johnson spreader insulators, but effective balanced line can be made by using PVC tubing, with the ends sliced to insert soft copper wire. When not wet its a very effective component in my antenna system. I've been using a 131' center fed Zepp with ladder line and Cecil Moore's (W5DXP) "non-tuner" for about 10 years and am very pleased with the results. See http://www.w5dxp.com/notuner.htm for details. And my vote for the best "all purpose" HF antenna of all time. Nearly an entire book on transmission line theory and antenna radiation behavior can be learned just by understanding the mechanics of the W5DXP antenna.
