The Sutton Coldfield transmitting station is a broadcasting and telecommunications facility located in Sutton Coldfield, Birmingham, England. It has broadcast terrestrial television signals every day since 1949 and is thus the oldest working television transmitting station in the world. ==History== On 17 December 1949, it became the first television transmitter to broadcast outside London and the Home Counties, bringing BBC Television to viewers outside of the south-east of England for the first time. A new mast was built around 1983 to replace the original structure, primarily to support new mixed-polarisation FM antennas. A 240.2m temporary mast was erected alongside the original mast in the spring of 2009 so that work could proceed in raising the height of the original mast by 31m (to a total height of 270.5m). After four years in service and almost a year after the completion of digital switch over, the temporary mast was removed during August 2013. All analogue TV transmissions ceased on 21 September 2011, as part of the digital switchover. This made it one of the oldest transmitters in the country to formally end analogue broadcasts. 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「Sutton Coldfield transmitting station」の詳細全文を読む スポンサード リンク
