I'm going from memory so... I've seen a video of a simple detector. In the
video the guy ran along the feedline while transmitting low power. You could
see if there was a signal on the outside of the cable. I'll look later to see
if I find. Fred KB4QZH

Re: Topband: 160M shunt fed choke One way to tell if a choke is needed I would
think, is to add say, a randomlenght of coax, 20 - 40 ft, to the shack end of
you coax and see if yourSWR changes. If so, then a then a choke could help.Jim,
does this sound like a reasonable test? I'm no expert on verticalantennas, just
my experience.Ray,N6VR/W7YAOn Thu, May 28, 2020, 11:42 AM Jim Brown
