I can easily blow N connectors out. When I replace them with less
expensive easier-to-install UHF connectors of good quality, I never
have connector problems. At HF, N's are good to 1500 watts or so
if SWR is low. Hardly a "high-power" connector by anyone but a
QRP club members standards. Teflon UHF's will take almost ten
kW without problem in the same situation.
I'd never use an "N" connector, unless it is an impedance critical
system or a system above maybe 250 MHz. The N has the same
approximate internal dimensions as a BNC, no matter how you
install it.
As a matter of fact if you remove the bayonet ring from a male
BNC, you can use it as a quick disconnect connector for N
females.
