I've been reading a bunch of articles this afternoon on feedline radiation in coax, and the use of ununs, baluns, beads etc. That has resulted in replacing ignorance with confusion. It looks to me like there are three options. 1. Build/buy a unun 2. Buy ferrite cores to put on the coax for a couple of feet. 3. Just leave it alone unless you get RF in the shack, etc. I have an AH-4 tuner which is coax fed. I can put a unun in between the transmitter and the tuner, at/near the tuner. It takes a maximum of 120 watts so I don't plan high power with this set up. I can also pop 10 or so ferrite beads/cores on the feedline up at the tuner. What approach is most satisfactory?
