Template:Infobox UK Transmitter

The Belmont transmitting station is a broadcasting and telecommunications facility next to the B1225, Template:Convert west of the village of Donington on Bain in the civil parish of South Willingham, near Market Rasen and Louth in Lincolnshire, England ({{#if:TF217837|[[Ordnance Survey National Grid|{{#if:Template:Yesno|Grid|grid}} reference]] {{#invoke:Ordnance Survey coordinates|oscoord|TF217837_region:GB_scale:25000|TF217837|name=}}}}). It is owned and operated by Arqiva.

It has a guyed tubular steel mast, with a lattice upper section. The mast was shortened in April 2010 and is now Template:Convert in height.<ref name="planningapp">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Before this it was Template:Convert high and was considered to be the tallest structure of its kind in the world (taller masts, such as the KVLY-TV mast in the United States, use steel lattice construction), and the tallest structure of any type in the United Kingdom. After the top section was removed, the mast's reduced height relegated it to the second-highest in the UK after Skelton in Cumbria.

Despite the mast being shortened it can be seen in daylight on clear days from most areas close to and within the Lincolnshire Wolds. On clear nights its bright red aircraft warning lights can be very widely seen across much of Lincolnshire from as far north as the Humber estuary and Barton-Upon-Humber; from the west of the county it can be seen from Lincoln, Gainsborough and Grantham; from the south of the county it can be seen from Spalding and Bourne; and from the east it can be seen from Skegness, Mablethorpe and most areas along the Lincolnshire coast. The lights can also be seen from many parts of Nottinghamshire, coastal areas of North West Norfolk and a few parts of Derbyshire on very clear nights.

ConstructionEdit

A planning application was made in October 1963 to Louth Rural District.<ref>Grimsby Evening Telegraph Thursday 17 October 1963, page 12</ref> Work had started by April 1964.<ref>Skegness Standard Wednesday 22 April 1964, page 11</ref>

The foundations were laid on 30 June 1964.<ref>Grantham Journal Friday 3 July 1964, page 16</ref> The concrete foundation was built by the end of October 1964, with tube sections being added from November 1964 at the site, near Benniworth.<ref>Louth Standard Friday 30 October 1964, page 23</ref>

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.<ref>Grimsby Evening Telegraph Wednesday 1 July 1964, page 7</ref><ref>Horncastle News Friday 3 July 1964, page 6</ref>

The mast was constructed in 1965 and it came into service on 20 December of that year. As built it was a tubular pipe Template:Convert long by Template:Convert in diameter, surmounted by a Template:Convert 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.<ref>Times Friday 10 September 1965, page 9</ref>

In September 1967, meteorological equipment was added to the Template:Convert mast extending its height to Template:Convert. The imperial measurement was the accepted value quoted by publications including the 1993 edition of the Guinness Book of Records.<ref name="Guinness 1993">Guinness Book of Records 39th Edition (1993), page 93 – Template:ISBN</ref> The metric measurement quoted by the current owners is Template:Convert 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 Template:Convert high.

CoverageEdit

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.

TransmissionEdit

Due to bad weather in late 1965, it did not offer a full ITV service until Monday 16 May 1966. But BBC and VHF radio would start in autumn 1966. Emley Moor, its twin, came into full service on 15 August 1966.<ref>Louth Standard Friday 27 May 1966, page 23</ref>

The transmitters were not installed by the end of September 1966, but BBC equipment was being tested by early 1966,<ref>Lincolnshire Standard Friday 30 September 1966, page 8</ref> with full BBC service on Saturday 19 November 1966, and test transmissions from 5 November, with Peterborough able to receive these broadcasts.<ref>Peterborough Evening Telegraph Wednesday 9 November 1966, page 6</ref> This was the same month that Pontop Pike also began transmissions. Tacolneston went into full service on 9 September 1967.<ref>Horncastle News Thursday 10 November 1966, page 7</ref>

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 <ref>Grimsby Evening Telegraph Friday 21 February 1969, page 1</ref><ref>Skegness Standard Wednesday 26 February 1969, page 3</ref>

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, <ref>Lincolnshire Standard Friday 12 February 1971, page 11</ref> ITV would be later on Monday 24 May 1971.<ref>Lincolnshire Standard Friday 14 May 1971, page 16</ref>

Transmitter powerEdit

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 clearanceEdit

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 (see graph). 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 frequencyEdit

Analogue televisionEdit

20 December 1965 – 19 November 1966Edit

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 1971Edit

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.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> On 19 March 1969, the Emley Moor mast collapsed, taking Belmont's BBC2 transmissions off-air for several days.<ref name="timeline">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

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)<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> after changes in the minor franchise areas.

It was always number 120.0 in the BBC/IBA numbering scheme for UHF stations<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>).

30 July 1974 – 2 November 1982Edit

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.<ref name="timeline" /> It was fed by a Post Office (later BT) microwave link from Leeds, allowing Yorkshire TV to supply Belmont with a separate 7-minute segment of their regional news magazine programme "Calendar", a Belmont titled version of Anglia's weather forecast, as well as having the ability to sell advertising separately in the Belmont and Emley Moor areas. The microwave link from Leeds to Belmont apparently ran via Emley Moor, where the IBA could insert test transmissions, such as Test Card "F"

30 March 1997 – 15 November 1998Edit

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.
