1. [RFI] Anyone correlated feedline common mode current levels with RFI / noise received? (score: 1): Author: Alan Higbie <alan.higbie@gmail.com>; Date: Fri, 7 Dec 2018 13:10:57 -0700; I know that we can minimize RFI / noise pickup by minimizing the common mode currents on our feed lines. And, that we want the choke to reduce common mode current to near zero. I have seen **differen; /archives//html/RFI/2018-12/msg00033.html (8,629 bytes)

I use these as "ground-breakers" in the shack on the end of a long coax cable to a low-gain rx-only antenna. This style was particularly ef; /archives//html/RFI/2018-12/msg00034.html (9,237 bytes)
