Reigate transmitting station is a television and radio transmitting tower in southeastern England. It is located on the North Downs at Reigate Hill about one mile (1.6 km) north of the town of Reigate at junction 8 of the M25 motorway where it intersects with the A217 road. Another telecommunications tower is located adjacent to the Reigate broadcasting tower, both sites are owed and operated by Arqiva.
The station was primarily built to provide uhf television to the towns of Reigate and Redhill which are screened from the London transmitter at Crystal Palace by the North Downs. However, from its high position on Reigate Hill (site height 226 metres (741 ft)) the transmitter provides secondary coverage to a large area of south Surrey and northern areas of West Sussex. [1]
The original tower built in 1966 was some 46m in height. In the late 1990s with the need to add additional services to the tower, such as digital radio, the tower was replaced with a new structure some 18m taller.
History

When the station was brought into service on 24 October 1966 it only carried
The Reigate transmitter was included in the roll-out of the first 81 transmitters to carry the UK digital terrestrial television service when it was launched in the UK. The service from the transmitter officially began in September 1999. Six digital multiplex signals were transmitted at low power from the station in addition to the four existing analogue television services. When the Channel 5 analogue service was added in 2003 it brought total number of television signals transmitted from the station to eleven. [3]
On 18 April 2012 all the analogue television services at Reigate transmitter were switched off as part of the UK Digital Switch Over project. Three of the frequencies that had been used for the analogue service were transferred to the digital television service while the highest frequency above 800MHz was released for use by mobile 4G services. All six digital television transmissions were increased in power to 2 kW.[3]
In 2014 the UK telecommunications regulatory Ofcom decided that the 700 MHz band should be cleared of digital television to be used for mobile broadband services by the summer of 2020. As a result, on 21 March 2018 three of digital television signals transmitted from Reigate were moved in frequency to lower frequency channels. [4] [5] [6]
On 16 October 2019 the local television multiplex entered service at the transmitter. It operates as a single-frequency network with the Crystal Palace and Croydon transmitters.[7]

When the BBC launched its Digital Radio national service on 27 September 1995 the Reigate transmitter was included in the network to strengthen coverage in South London, East Surrey and North Sussex.[2] The first national commercial network, Digital One, was added to the transmitter on 23 September 1999 and a second national commercial network, Sound Digital on 29 February 2016.
In addition to the 3 national networks, the three London local digital radio services were added as they launched: London 1 on 13 June 2000 (CE Digital), London 2 (Switch London) on 23 November 2000 and London 3 (DRG London) on 18 January 2002. On 12 December 2013 a local digital radio service for Surrey was added by MuxCo. [2] [9] [10] [11]
