Croydon transmitting station

From Wikipedia, the free encyclopedia

The Croydon transmitting station is a broadcasting and telecommunications facility located in Upper Norwood, London, England (grid reference TQ332696), in the London Borough of Croydon, owned by Arqiva. It was founded in 1955 and initially used a small lattice tower. The tower present on the site today is 152 metres (501 feet) high and was built in 1962.

The Croydon Transmitter was originally used to broadcast the London ITV signal on VHF Band III. When UHF broadcasting began the nearby Crystal Palace Transmitter was used. VHF television was discontinued in 1985, and the Croydon Transmitter was not used again for regular TV broadcasting until 1997, when a new directional UHF antenna, designed to avoid interference with continental transmitters, was installed to carry the newly-launched Channel 5 (later five) in the London area. It still carries five's analogue signal, although its digital terrestrial service uses Crystal Palace. Croydon also has reserve transmitters for ITV1 and Channel 4, but these are only used in the event of engineering works or a failure at Crystal Palace.

The site is also a maintenance base for transmitter teams and houses one of four Regional Operations Centres or ROCs.
