Maybe if you don't try to cover all of 75 or 160, but I've blown out N
connectors (Amphenols no less) running no more than the legal limit on
75 a number of times. I use a tuner so I can cover all of both bands and
have not had good luck with N connectors on either of those two bands.
On 40 I not only can use N connectors, but RG8X, and CNT240 at the legal
limit.

Not a problem here. The legal limit on 440 is 50 watts.<:-((
