The Belling-Lee connector or '''IEC 169-2 connector''', more often simply known as '''TV aerial plug''' or ''' PAL connector''', is the traditional European Antenna Connector for TV Set s and FM-radio receivers. It is the oldest coaxial RF Connector still commonly used today. It connects a receiver to a terrestrial VHF / UHF roof Antenna , antenna amplifier, or CATV network, via a Coaxial Cable . HISTORY It was invented at Belling & Lee Ltd in Enfield, England , around 1922, at the time of the first BBC broadcasts. It was originally only intended for Medium Frequency broadcasts, where accurate impedance matching of an antenna connector is not a concern. BELLING-LEE VS OTHER CONNECTORS Unlike the coaxial F Connector used today for the same purpose in North America, the IEC 169-2 connector is ''not'' matched to the 75-ohm Impedance of the antenna cable used. The lack of impedance matching causes Signal Reflection s in the cable, leading to noticeable signal distortion on VHF and UHF frequencies (but not MW or Shortwave ).
MINIATURE BELLING LEE 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). It is not known who made them or any other name for the connector. It looks similar to a standard Belling Lee plug but is about half the size. The standard Belling Lee plug is about 33 mm long and 9.5 mm diameter (mating surface), the Miniature Belling Lee is about 17 mm long and 4.4 mm diameter. REFERENCES
