Your feed line will do the job by itself so no additional "balun" is needed. Keep in mind that a 1:1 balun is really just a length of feed line, usually wound on a toroidal core to make the required length shorter than if it was in open air. The "old-school" baluns were just a pair of air wound

Jim, You might find that on some bands your antenna tunes better with a 1:1 balun and on others with a 4:1. Therefore, I recommend the Elecraft balun, which is switchable. It's rated at 250w so it should be adequate. 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ On 4 Feb
