Hi Rick - actually, the flashover was out at the base of the tower, and
the Polyphaser is in the shack window. I've had a few of these before,
and they generally leave a little soot-like material on the insulator,
which I think is conductive to a degree. I suspect they start with
failure of the tape job, leading to moisture infiltration. Because
there had been lightning last night (no near misses or even visible
cloud-to-ground), I wondered about the Polyphaser, before I started
tracking sdown the failure

Pete,
Are you saying the Polyphaser is still ok? That the low R was caused by a path
within the adapter?
Interesting.
So we don't actually know if the gas tube fired or not then, do we? Because
maybe most or all the energy went to ground through the N-PL250 adapter before
it got to the place where the arrestor was mounted. I'm assuming the adapter
was out by the tower and the Polyphaser was near the entrance to the shack.
