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.
