It's probably a "C" connector - without dimensions or a scale in the 
picture, it's hard to tell.  Weatherproof, bayonet, good to 11GHz like an N.

about $40 each from Pasternack, $114 for Amphenol from Mouser.


There's also a 75 ohm BNC - but the Bayonet part is exactly the same 
size as a 50 ohm BNC.

The other possibilities are various high voltage BNC - some are larger 
in diameter, but a distinguishing feature is that the "nose" is longer 
to make the creepage distance between the connector longer.


[ someone probably got a "good deal" on surplus for those]
