KPA500 Faulting on high SWR on power rise

I just posted almost the exact thing. I should have read all of the posts
first.

It is interesting that coax has a much higher voltage rating than the
connectors however Amphenol UHF connectors rarely fail even after direct
lightning strikes.

The Amphenol voltage rating for UHF connectors is 500 V peak. So the
connectors could be another weak point.

I have never seen a properly installed UHF connector, in a matched system, arc.

I've observed many times an arc occur from the center pin to shell with
an unterminated line during a thunder storm.   No damage to the
connector occurred however.   Makes for an eerie dang sound too.
