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.

[Elecraft] 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.
