RF-wise an N-type and BNC-type connector are actually very similar.  The 
differences are basically in the outer shell for mechanical connection.  
To see how similar they are try this:

Take a BNC-Female and slide it into an N-Male connector.  Nice tight 
fit, except of course it doesn't actually mechanically stay together.   
Also, if you had a BNC-Male connector without the bayonette outer part 
that turns it would slide into an N-Female connector and would be a 
pretty good mate as well.  Also, I think an N-type connector is supposed 
to be quite weather-resistant (although I would always wrap one up to 
make it more weatherproof, however I don't think a BNC is 
weather-resistant without significant efforts to add weatherproofing. 

Somewhere I'd have to look for mechanical drawings of the N & BNC, but 
I'm sure they important parts, that is the pin or socket sizes are 
equivalent as well as the shield diameter parts.
