if you try to put a common mode choke at the antenna I can imagine difficulties with overheating etc as the voltage is high. I allow the unbalance current through the feeder and I stop it after the t
Huh? A proper common mode choke can handle legal limit at the feedpoint of centerfed dipole fed with coax. Study k9yc.com/RFI-Ham.pdf I allow the unbalance current through the feeder and I stop it af
The common-mode voltage at the feedpoint of an OCFD can be many times the differential voltage across the feedpoint. Take the common example of a 132ft wire fed 44ft from one end at a height of 35ft.
