The Llandrindod Wells transmitting station is a broadcasting and telecommunications facility located on high ground about midway between Llandrindod Wells and Rhaeadr, in Powys, Wales. It was originally built by the BBC,〔http://downloads.bbc.co.uk/rd/pubs/reports/1964-26.pdf〕〔http://downloads.bbc.co.uk/rd/pubs/reports/1956-24.pdf〕 entering service in 1961 transmitting the now-defunct 405-line VHF television system and the original three FM Radio services. Currently, the transmitter provides DVB-T digital television to the area, along with FM radio and a single multiplex of DAB digital radio. ==Specifications and history== Originally, the site has a guyed 65 m lattice mast erected on land that is itself about 440 m above sea level. Unusually for the era, when 405-line Independent Television came to the area in 1969, the ITV transmissions were hosted on the same mast as the BBC ones. UHF television was added to the site in late 1975, launching with just the three programme services that were active at the time. S4C was added in 1982 when it launched. 405-line television from this site was shut down in January 1985.〔http://www.pembers.freeserve.co.uk/405-Lines/Transmitters.gif〕 In 1991, the site was re-engineered. A self-standing 75 m lattice mast was erected on the site, the services were transferred from the old mast on 13 November 1991. The television broadcasts primarily cover the towns of Llandrindod Wells (to the east), Builth Wells (to the south) and Rhaeadr (to the northwest). 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「Llandrindod Wells transmitting station」の詳細全文を読む スポンサード リンク
