-- About BNC Cables --
BNC Cables are a type of
coaxial cable that use the BNC (Bayonet Neill-Concelman) connector
which is a common type of RF connector. BNC cables are usually used with:
- Amateur radio antennas
- Avaiation electionics
- Test Equipment
- Military Equipment
The BNC Connector an alternative to the
RCA connector when used for composite video on commercial video devices, although many consumer
electronics devices with RCA jacks can be used with BNC-only commercial video equipment via a simple adapter. BNC connectors
were commonly used on 10BASE2 thin Ethernet networks, both on cable interconnections and network cards.
BNC connections can also be found in recording studios. Digital recording equipment uses the connection for synchronization
of various components via the transmission of word clock timing signals.

Advanced Information
- BNC Connecotrs are usually applied to frequrencies below 3GHz and voltages below 500 Volts.
- BNC connectors exist in 50 and 75 ohm versions, matched for use with cables of the same characteristic impedance.
The 75 ohm types can sometimes be recognized by the reduced or absent dielectric in the mating ends.
The 50 and 75 ohm connectors are typically specified for use at frequencies up to 4 and 2 GHz respectively.
- At frequencies below 10 MHz the impedance mismatch between a 50 ohm connector or cable and a 75 ohm one has
negligible effects. BNC connectors were thus originally made only in 50 ohm versions, for use with any impedance
of cable. Above this frequency, however, the mismatch becomes progressively more significant and can lead to signal reflections.
