(重定向自Antenna socket)

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 (IEC 61169-2 radio-frequency coaxial connector of type 9,52) is commonly used for this purpose.
