BNC(Bayonet Neil-Concelman) connecter is a miniature quick connect/disconnect RF
connecter used for coaxial cable. It features three part of cable, at the center of the signal
lines and coax internal signal that surround outer conductor (shield), and insulation. BNC
connecters are made to match the characteristic impedance of cable at either 50 ohms or 75
ohms.
The 75 ohm types can sometimes be recognized by the reduced or absent dielectric in
the mating ends.
