Jim's correct - There ARE differences between 75 and 50 ohm coax
connectors ... especially Type N.

Not so. There is a very real physical difference between 50-ohm and
75-ohm
type N connectors. The 50-ohm male pins are bigger than the 75-ohm pins
and
will damage a 75-ohm female connector. Likewise if a 75-ohm male is
mated
with a 50-ohm female there will not be good electrical contact.

Does someone know how to tell a 50 ohm from a 75 ohm "N"?
The impedance is a characteristic of the coax cable, not the connector.
What does matter is what coax cable(s) the N connectors are designed
for,
such as RG8, RG58, RG214, etc. Take a look at
http://www.smelectronics.us/typencableconnectors.htm. This might help
you
match your connectors to their appropriate cables.
