The Belling-Lee connector or IEC 61169-2 connector (formerly IEC 169-2), known colloquially in countries which use it as a TV antenna connector, as a PAL antenna connector or simply as a TV aerial plug, is commonly used in Europe and Australia 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. It is one of the oldest coaxial connectors still commonly used in consumer devices.
It was invented at Belling & Lee Ltd in Enfield, United Kingdom around 1922 at the time of the first BBC broadcasts.
Miniature Belling-Lee connector
There is also a miniature Belling-Lee connector which was used for internal connections inside some equipment (including BBC RC5/3 Band II receiver and the STC AF101 Radio Telephone). The standard Belling-Lee plug is about 33 mm long and 9.5 mm diameter (mating surface); the miniature version looks similar but is only about 17 mm long and 4.4 mm diameter. Amalgamated Wireless Australasia (AWA) used miniature Belling-Lee connectors, internally, in their 25M series Land Mobile two-way radios in the early 1970s. The socket is a Belling-Lee L1465/CS whilst the plug is a Belling-Lee 1465/PF.
