This would depend on what sort of N connector you are using. The
ones with the captive pins won't have the problem.
The other connector you might look at is DIN-7/16 (I think that's 7
and 16 mm, not 7/16"). Better high power handling AND good impedance
characteristics AND waterproof. They're kind of expensive from
suppliers like RF Parts, but you might find a less expensive
source. I've seen them in the $20 range, and you'll find surplus
jumpers with DIN on both ends for even less.
