I don't use N on coax below 6M, but I do use N or BNC at 6M and above.

A year or so ago, I discovered an EXCELLENT N-connector for coax of RG-8 
and RG-213 size in a box of stuff that I bought from the estate of a 
slient key. It's made by Andros Manufacturing -- that's a machine shop 
business run by a ham in upstate NY. He sells through dealers, but it's 
hard to find them in stock.  I ended up buying them through WB0W, and I 
cleaned out their stock.  WB0W also tried to sell me Chinese copies of 
the Andros connector too, which I declined.

The connector is a unique 2-piece design that I've seen before only with 
crimp BNCs and some hard line connectors. Both center and shield solder 
to the same piece, then that screws into the large outer ring that mates 
with the other connector.  Easy to terminate, and quite robust. Worth 
chasing down if you use N connectors on this size coax.
