Hello all, I can’t easily locate discussions of the past about using a TV coax to twinned balun on the (balanced) RF input to my R-390A. I’d like to order some from Mouser (or other place) for use on HF radios and on FM receivers. Can anyone suggest some part numbers or descriptions I can search with? Thanks.
