Émetteur de Belmont

The Belmont transmitting station is a broadcasting and telecommunications facility next to the B1225, west of the village of Donington on Bain in the civil parish of South Willingham, near Market Rasen and Louth in Lincolnshire, England (). 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 in height. Before this it was 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. 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. The foundations were laid on 30 June 1964. 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.
