he BNC connector (Bayonet Neill–Concelman) is a common type of RF connector used for coaxial cable. It is used with radio, television, and other radio-frequency electronic equipment, test intstruments, video signals, and was once a popular computer network connector. BNC connectors are made to match the characteristic impedance of cable at either 50 ohms or 75 ohms. It is usually applied for frequencies below 3 GHz and voltages below 500 Volts.
