I feed my tower at a height of 21m against one radial and have KLM yagis mounted at 25, 31 and 44m (top of tower). So far I never had a problem by running high power on 160m and no change in SWR on the KLM antennas. However, I don“t use the original baluns but home made half wave 1:4 Baluns made from 1/2" Cellflex.
73 Peter, DJ7WW -----Original Message----- From: Topband [mailto:[email protected]] On Behalf Of Ron Spencer Anyone have problems running a KLM antenna with the 4:! balun and elements insulated from the boom (stock KLM config) on a shunt fed tower for 160? I ask because I have a 6 element 10 on the top of my shunt fed tower and now, after running a kw on 160, the antenna's swr has gone over 2:1 where before it was pretty flat at about 1.2:1 or so. Any ideas?
