[TowerTalk] PL-259 Voltage Breakdown

[Steve Katz]

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
of part.

500 V breakdown, or working is unrealistic for a good connector. IIRC
that 
is about what teflon is rated per mil. Even air, which you have between
the 
conductors at the interface between connectors would be much higher than
500 
V .

I've run as high as 6KV on them.  Hy-pot one and it'll probably be good
for 
about 12KV, but I'd not want to run one that high.
