81. Re: [TowerTalk] common mode chokes, baluns and multiband, doublets (score: 1)

Exactly. My approach, when discussing baluns, is to present the "balun" as a "function," not necessarily a "thing." The balun "function" is to transfer power between balanced and unbalanced systems w

Nice of G3TXQ to so liberally quote my work:-) I have a problem with W7FG recommending 4:1 baluns. (http://trueladderline.com/all-baluns/)  I suspect the thinking is that because the line is high imp
