The Lichfield transmitting station is situated close to Tamworth in Staffordshire in the West Midlands between the A5 and A51. The nearest geographical feature is Hopwas Hill. The station is owned and operated by Arqiva. The mast is known locally as Hopwas mast or Hints mast. ==History== The station was the main 405-line ITV transmitter for the Midlands from 1956 until 1985. It has a tall guyed mast. The station came on air on 17 February 1956, using two 5 kW transmitters and a 16-stack antenna mounted on a 450ft tall Eiffelized tower. This tower was replaced by the tall mast which came into service on 18th July 1961. The 450ft tower was dismantled in 1962 and shipped to Jersey, Channel Islands and re erected at Fremont Point on the north of the Island. 625-line colour transmitters for the region were all co-sited at the nearby Sutton Coldfield transmitting station until 1997, when Lichfield began broadcasting Channel 5 in the Midlands. At 1000 kW on C37 it was the most powerful Channel 5 transmitter in the country. Before the digital switchover, Lichfield effectively worked in conjunction with Sutton Coldfield (4 miles to the SW) to supply the full five analogue channels. Reception of Channel 5 from Lichfield was also receivable at viewable quality throughout the borders of North Wales. All analogue TV transmissions ceased on the 21 September 2011, as part of the digital switchover. A temporary HD multiplex BBC B (Mux HD) on C34 was moved to the Sutton Coldfield transmitting station on C40+ (626.2 MHz) thereby ceasing all analogue and digital television broadcasts from the Lichfield transmitter. 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「Lichfield transmitting station」の詳細全文を読む スポンサード リンク
