[TowerTalk] Feedline (choke) question

[David Gilbert]

Brian, I didn't say there shouldn't be any current.  I said there isn't 
any current that just goes to ground and stays there ... as in bleeding 
it off.  EZNEC doesn't show that either.  It just shows current going 
back and forth between the earth and the coax ... and when it goes back 
to the coax where do you think it goes?  It doesn't just pile up at that 
spot on the coax .. it goes wherever it was going to go anywhere, either 
back to the antenna or to the transmitter.

Why do you think otherwise?
