BNC connector is a miniature quick connect/disconnect radio frequency connector used for coaxial cable. It features two bayonet lugs on the female connector; mating is fully achieved with a quarter turn of the coupling nut. BNC connectors are used with miniature-to-subminiature coaxial cable in radio, television, and other radio-frequency electronic equipment such as CCTV, test instruments, and video signals. The BNC was commonly used for early computer networks. BNC connectors are made to match the characteristic impedance of cable at either 50 ohms or 75 ohms. They are usually applied for frequencies below 4 GHz and voltages below 500 volts.

The BNC was originally designed for military use and has gained wide acceptance in video and RF applications to 2 GHz. The BNC uses a slotted outer conductor and some plastic dielectric on each gender connector. This dielectric causes increasing losses at higher frequencies. Above 4 GHz, the slots may radiate signals, so the connector is usable, but not necessarily stable up to about 11 GHz. Both 50 ohm and 75 ohm versions are available.

BNC connectors are most commonly made in 50 and 75 ohm versions. Video and applications primarily use 75 ohm connectors, while 50 ohm connectors are used for data. We can tell the difference between the two by looking for the dialectric. The 50 ohm connector features a white dialectric surrounding the center pin, while the 75 ohm BNC connector is surrounded by air (no dialectric).

50 ohm and 75 ohm BNC connectors will mate with each other. At frequencies under 10 MHz the impedance mismatch will not have any affect. If you are above 10 MHz the chances of signal distortion become more significant.

The benefit of this twist on connector are they do not require any termination tools other than the strip tool. They are great for a quick installation.
