TV aerial plug
A TV aerial plug is a colloquial name for a connector used to connect coaxial cables with each other and with terrestrial VHF/UHF roof antennas, antenna signal amplifiers, CATV distribution equipment, TV sets and FM / DAB-radio receivers.
In Europe and Australia the Belling-Lee connector is commonly used for this purpose.
In other parts of the world the F connector is most commonly used.
