[TowerTalk] Higher power RF connector?

I'll second that.

In dry connectors with controlled SWR and no other problems
N's are fine at a few KW. I've seen them handle as much as
10kW at HF in controlled environments with limited duty
cycle.

Most of the medium high power (1 to 5 kW) ISM equipment I
see uses HVN connectors.

The  problem is the close air-gap spacing inside the
connector and the small pin severely limit ability of "N"
connectors to take abuse. The spacing and pin size are
almost exactly the same as a BNC connector. Get any moisture
in it, have a lightning hit, have a high SWR, and the N
connector is often history.
