Any conductor carrying RF current WILL radiate it. That's antenna
action. The "hum" and "buzz" described in my earlier post are NOT RF,
they are baseband (60 Hz and harmonics).
The mechanism whereby a coax feedline is carrying RF current into our
shack producing hum is that the current couples into electronics
(usually by a Pin One Problem) and changes the bias state of some gain
stage.
