About the BNC Interface

The BNC interface (bayonet Neill-Concelman) feature a two stud bayonet-coupling mechanism, which is useful for frequently coupled and uncoupled RF connections with frequencies up to 4 GHz. This series of connector can be commonly found in test & measurement applications as well as military communications. The connectors are also available in 75 ohm versions for commercial telecom and CATV applications.
