The current balun should eliminate QRM a little, and eliminate unbalanced current flow on the balanced coax line. With the balun placed at the ATU, the feedline is balanced up to the ATU. When placed at the TRX, the coax will be part of the radiation pattern so HF will be introduced in the shack. text/html 2026-02-06T09:39:57+00:00 Anonymous (anonymous@undisclosed.example.com) http://172.16.0.10:8087/balun_tests?rev=1770370797&do=diff Balun tests Current balun placement in the feedline tests Current balun or no current balum text/html 2026-02-06T09:39:57+00:00 Anonymous (anonymous@undisclosed.example.com) http://172.16.0.10:8087/baofeng_rubber_ducky?rev=1770370797&do=diff Baofeng Rubber Ducky Specs: ManufacturerBaofengTypeU-V AntennaOperating frequency136-174MHz and 400-520MHzGainNA This antenna was bundled with my Baofeng UV-82 handheld VHF/UHF handset.
