Belmont transmitting station

A planning application was made in October 1963 to Louth Rural District. Work had started by April 1964. The foundations were laid on 30 June 1964. The concrete foundation was built by the end of October 1964, with tube sections being added from November 1964 at the site, near Benniworth. It would be the seventh highest mast in the world. The first 900 ft would be a 9-ft diameter steel cylinder, with the rest a steel lattice. There would be a 12 ft cylinder around this lattice, with the top 150 ft being 9 ft wide. 1200 cubic feet of concrete was poured into its 32 square feet foundations. 12 people would work on the site. The mast was constructed in 1965 and it came into service on 20 December of that year. As built it was a tubular pipe long by in diameter, surmounted by a lattice upper section (an identical mast was constructed in 1964 at Emley Moor near Huddersfield in Yorkshire, but the other mast collapsed due to guy failure caused by icing and high winds on 19 March 1969). Its ropes weigh 85 tons, made by British Ropes, with steel from Steel, Peech and Tozer of Templeborough in South Yorkshire. The column weighs 210 tons and has 375 segments, with steel from United Steel Companies at Scunthorpe in northern Lincolnshire. In September 1967, meteorological equipment was added to the mast extending its height to . The imperial measurement was the accepted value quoted by publications including the 1993 edition of the Guinness Book of Records. The metric measurement quoted by the current owners is shorter. Between October 2009 and April 2010, the mast was shortened as part of the Digital Switchover works. Most of the top section above the fifth stay level was removed (along with the sixth stay level) and the mast now stands high. ==Coverage==

From its location, high in the Lincolnshire Wolds, it broadcasts digital television and both analogue and digital radio to Lincolnshire, eastern Yorkshire, northern parts of Norfolk and some eastern parts of Nottinghamshire. Belmont is the main transmitter that covers the cities of Hull and Lincoln. When it was first operated it transmitted (amongst others) ITV station Anglia Television. Following a re-organisation of ITV coverage in 1972, from 1974 it started transmitting neighbouring station Yorkshire Television instead, which it continues to do to this day. ==Transmission==

Due to bad weather in late 1965, it did not offer a full ITV service until Monday 16 May 1966. BBC and VHF radio would start in autumn 1966. Emley Moor, its twin, came into full service on 15 August 1966. The transmitters were not installed by the end of September 1966, but BBC equipment was being tested by early 1966, with full BBC service on Saturday 19 November 1966, and test transmissions from 5 November, with Peterborough able to receive these broadcasts. This was the same month that Pontop Pike also began transmissions. Tacolneston went into full service on 9 September 1967. On 19 February 1969 wintry weather caused an eight-hour power cut, and staff were cut off by snow drifts, with a small amount of food. One month later, wintry weather brought down an identical mast, Emley Moor. Emley Moor was the highest man-made structure in Europe The first colour tests from Monday 18 January 1971; Sandy Heath began full colour broadcasting on 8 February 1971; Tacolneston went colour on 1 October 1970. Full colour on channel 22 for BBC1 began on Monday 15 February 1971, ITV would be later on Monday 24 May 1971. It started stereo broadcasts on radio from Saturday 25 August 1973, along with other northern sites. ==Transmitter power==

In the analogue era Belmont, at 500 kW E.R.P. for the four main analogue television channels, was one of the most powerful transmitters in the UK, though there were four UK transmitters which were more powerful; Sutton Coldfield, Crystal Palace and Sandy Heath were all at 1000 kW and Emley Moor was 870 kW. After digital switchover Belmont's digital transmitting power was 50 kW for SDN (previously Mux A), 100 kW for Arqiva A & B (Mux C, D) and 150 kW for BBC A, D3&4 and BBC B (Mux 1, 2, B). ==700MHz clearance==

On 4 March 2020, Belmont was due to complete its 700MHz clearance and will become an A group transmitter, excluding the temporary MUXES 7 and 8. Since Belmont started out as an A group for (just) analogue it returns to that band after being a wideband for 21 years. Technically the advent of C5 analogue complicated the issue for a few months prior to (dual) running digital transmissions started in 1998. ==Services listed by frequency==

Analogue television 20 December 1965 – 19 November 1966 First transmissions from the site: ITV's 405-line television service was fed by off-air reception of Mendlesham at Great Massingham in Norfolk, with an onward microwave link to Belmont via an intermediate point at Winceby in Lincolnshire. 19 November 1966 – 24 May 1971 The BBC's services came online on both VHF and UHF. BBC1 was initially fed by means of an off-air rebroadcast of Holme Moss but this was plagued by co-channel interference from the continent. BBC2 was an off-air rebroadcast from Emley Moor. On 19 March 1969, the Emley Moor mast collapsed, taking Belmont's BBC2 transmissions off-air for several days. Despite the programme sources on VHF and UHF being (for many years) off-air rebroadcasts of other transmitters in the vicinity, Belmont was always regarded by the BBC as being a "main station" both on VHF and UHF. The IBA initially regarded it as a relay of Mendlesham (and numbered it 14.2 in their numbering of VHF stations) but from 1974 it became a "main station" for Yorkshire Television (renumbered as 20.0 in the IBA's numbering of VHF stations) after changes in the minor franchise areas. It was always number 120.0 in the BBC/IBA numbering scheme for UHF stations). 24 May 1971 – 30 July 1974 ITV's UHF service began. 30 July 1974 – 2 November 1982 After changes to the regional structure of ITV in 1972, Belmont stopped being a relay of Mendlesham and became a main station for Yorkshire TV. in mid-1982, and when Channel 4 began formal transmissions in November that year it was radiated on UHF from the site: 30 March 1997 – 15 November 1998 Belmont started transmitting the UK's final terrestrial analogue UHF TV service: Channel 5. This was done well out-of-band and at reduced power compared with the main group. Analogue and digital television 15 November 1998 – 3 August 2011 Belmont began transmitting digital TV, with the new digital multiplexes spaced far from the existing analogue channels. In July 2007 it was confirmed by Ofcom that Belmont would be remaining a wideband transmitter after digital switchover. 3 August 2011 – 17 August 2011 BBC2 closed on UHF 28. BBC1 was moved on to that channel for its final three weeks of service. Pre-DSO Multiplex 1 (BBC) on UHF 30 was closed and was replaced by BBC A on UHF 22. Digital television 17 August 2011 – 26 November 2013 All the remaining analogue and existing digital signals were turned off and replaced with higher-power digital signals. • Arqiva A and Arqiva B were limited to 4 kW until 23 November 2011, when they were increased to 100 kW. 26 November 2013 – 4 February 2020 Local TV, carrying Estuary TV, and Arqiva C, carrying additional HD services, launched on 26 November 2013. 5 February 2020 – 3 March 2020 Arqiva A moved from UHF 53 to UHF 23, in accordance with the 700MHz clearance. 4 March 2020 – 24 June 2020 Arqiva B moved from UHF 60- to UHF 26, and a power increase of the Local multiplex, in accordance with the 700MHz clearance. 25 June 2020 – Present COM 8 was switched off permanently in accordance with the 700MHz clearance programme. Analogue radio (FM VHF) 19 November 1966 – 11 November 1980 11 November 1980 – February 1992 BBC Radio Lincolnshire started broadcasting. BBC Radio 1 officially launched in 98.3 on 27 July 1990 February 1992 – present day Lincs FM (launched 1 March 1992) and Classic FM (launched 1 September 1992) join the set of FM broadcasts.
