“Balun” is also misleading because “balanced” transmission line is a misleading idea. Whether the transmission line is coax or two-wire, it can carry both differential mode and common mode currents.
I prefer the words “choke” and “transformer”. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Oct 14, 2020, at 10:14 AM, Alan - G4GNX <[email protected]> wrote: > > Jim.
