웹2024년 2월 2일 · Another option is to examine your SWR sweep across the band at the radio end, of course, and figure out which current balun would best serve your purposes. I have a tall 165 foot dipole fed with about 62 foot of ladderline and it is resonant or close on several bands using a 6:1 balun. Do your measurements with a 1:1 and go from there. 웹2024년 4월 7일 · As soon as I transmit on the end fed, it seems that RF is getting back into the shack, because the serial port on my computer locks up and I can no longer control the radio via the computer. This never happens when I transmit on the hex beam. I have a 1:1 choke balun where the coax enters my shack but it still doesn't seem to solve the issue.
