[Wswss] Power handling capability of type N connectors?

[N3IZN at aol.com]

Well I’m slowly getting my tower up. The question I have is about how  much 
power the N type connectors can handle. I've seen it reported differently  on 
the various websites. I plan on running Andrews Heliax from the shack to the  
top of the tower and terminating it with an N female connector. Then use  
LMR400Flex from there to the antenna. On 1296 and 432 I doubt if I will ever  come 
near the max power of the connector. On 220 & 144 I might and on 6 and  HF I 
expect to be nearing legal limit. Any comments or experiences? 
Thanks in advance. 
Some questions I might get: 
Why are you using heliax on 6 and HF? 
Why are you using N connectors? 
Answer: I get it surplus for free. 
Depending on the feedback I get I guess I could break down and buy some  7/16 
DIN connectors for LMR 400. Yeah I get the DIN females surplus  too.
