1. [TowerTalk] Full wave loop on 80m : Impedance 50 or 75 Ohms?? (score: 1): Author: vk2lee@maxnet.net.au (Lee Noonan); Date: Mon Jan 27 22:18:18 2003; I have been using Full wave loops on 80m since 1987 and have always used 75 Ohm coaxial cable as feedline without a Balun. I know of other hams that use a Balun on a full wave loop. My Loop is Rectan; /archives//html/Towertalk/2003-01/msg00468.html (8,186 bytes)
