" And you don't need a hail-mary super choke for the job. " Hi Guy: I'm going to try elevated radials on my shunt-fed tower. I was thinking about constructing an "Ugly Balun" for the job with 4" PVC and Bury-Flex. What kind of choke do you use / recommend ? About how much coax should be wound on the 4" PVC for this job ? 73, Jamie WB4YDL
