Re: N connector

Liviu Babi <electronicguest@...>

I am asking that just because I use only N connectors at 1.7 KW out for 144 MHz EME for last 3 years and a friend of mine told me I was lucky. Not any faults even in 24 hours EME contest in digital mode. Have very good swr 1:1 at 1,7 KW out.

Hi Liviu
A good N type should be capable of handling 1kW so long as the VSWR is low and the plug and socket are in good condition. Be aware that recently manufactured cheap commercial N types may use polypropylene insulation instead of PTFE, and they will melt at high powers.
Worn N types may have poor female centre contact pressure, leading to local hot spots that can destroy the connector. Unused "Precision N" female connectors may be worth looking for - they usually have 6 or 8 gold plated splines on the female connector inner and should exhibit lower contact resistance.
