[TowerTalk] PL-259 Voltage Breakdown

I've had PL-259s fail hipot (set to 3mA trip point) at way under 6 kV.
It depends on the air around them. Air's a great dielectric when it's
dry (0% humidity) and a lousy one when it's wet (100% humidity).
Without a controlled environment, you can't define the BV of this kind

500 V breakdown, or working is unrealistic for a good connector. IIRC
is about what teflon is rated per mil. Even air, which you have between
conductors at the interface between connectors would be much higher than
I've run as high as 6KV on them. Hy-pot one and it'll probably be good
about 12KV, but I'd not want to run one that high.
