female,the BNC without its locking ring will plug into an "N"female!

The N male pin is usually larger than the BNC fem center receptacle. This
results in a BNC female with increased loss or breakage due to fatigue.
This was known in the extended technical community of my experience as a
GRONK!


Like I said, we "permanently" adapt N to BNC inside the lab. I've never
used an N in a situation where a BNC wouldn't have worked*. I guess the
threads make the connection more permanent, but now we have the TNC for
that.

*Check that. I did need a 75 Ohm N jumper once to get from a 7/8" line
to the back of a Moseley STL receiver.
