Just as a further note, 50 and 75 ohm BNCs will interconnect (the metal parts are the same, with the impedance difference coming from the dielectric used) but 50 and 75 ohm N connectors don't -- the center pin of the 50 ohm version is thicker. If you mate a 50 ohm male with a 75 ohm female, you will damage the female. If you mate a 75 ohm male with a 50 ohm female, the connection will range from shaky to nonexistent depending on how well centered the pin is.
