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

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.
