The C connector is a type of RF connector used for terminating coaxial cable. The connector uses two-stud bayonet-type locks. The C connector was invented by Amphenol engineer Carl Concelman. It is weatherproof without being overly bulky. The mating arrangement is similar to that of the BNC connector.[1] It can be used up to 11 Ghz, and is rated for up to 1500 volts.
