Jim, I forgot to ask. Do you have a bare-wire dipole
with no DC connection between the elements? If so,
does the coax connector ever arc when you disconnect
it from your system?

The first time I encountered this phenomenon in Arizona,
my G5RV coax connector was arcing while connected to
my IC-745. I disconnected the coax from my transceiver
and tossed it on the floor. It woke me up arcing and
scorching my carpet. Shorting the coax conductors
cured the arcing problem.

It was a clear starry night with the wind blowing about
30 mph. I have a hard time diagnosing that as a corona
problem.
