The Belmont transmitting station is a broadcasting and telecommunications facility, situated next to the B1225, one mile 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.〔(【引用サイトリンク】title=Arqiva planning application )〕 Prior to this it was 387.7 m 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), the tallest structure of any type in the United Kingdom and also the tallest structure within the European Union. After the top section was removed the mast's reduced height relegated it to 14th highest structure in the EU and second highest in the UK after Skelton. The current world's tallest guyed tubular steel mast is TV Tower Vinnytsia in Ukraine. Despite the mast being shortened it can been seen in daylight on clear days from most areas close to and within the Lincolnshire Wolds and on clear nights its bright red aircraft warning lights can be very widely seen across much of Lincolnshire from as far north as the River Humber and Grimsby and from west of the county it can be seen clearly from both Lincoln, Gainsborough and Grantham and from the south of the county it can be seen clearly as far away as Spalding and Bourne and can also be very clearly seen in the east of the county as far away as Skegness, Mablethorpe and most areas along the Lincolnshire Coast. The aircraft warning lights from the mast can also be seen from many parts of Nottinghamshire, coastal areas of North West Norfolk and even a few parts of Derbyshire on very clear nights. ==Construction== The mast was constructed in 1965 and it came into service on 20 December of that year. As built it was a tubular pipe 900 feet long by 9 feet in diameter, surmounted by a 365 ft lattice upper section. (An identical mast was constructed in 1964 at Emley Moor near Huddersfield in Yorkshire, but that mast collapsed due to guy failure caused by icing and high winds on 19 March 1969.) In September 1967 meteorological equipment was added to the 1,265 ft mast extending its height to 1,272 ft (387.7m). The imperial measurement was the accepted value quoted by a number of publications, including the 1993 edition of the Guinness Book of Records.〔Guinness Book of Records 39th Edition (1993), page 93 - ISBN 0-85112-978-1〕 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 351.65 m high. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Belmont transmitting station」の詳細全文を読む スポンサード リンク
