It was originally built in the 1970s as a fill-in relay for UHF analogue television. It consists of a 25 m self-supporting lattice mast standing on a hillside which is itself about 180 m above sea level (about 150 m above the town). The transmitters are beamed southwards to cater for those digital terrestrial TV subscribers in Port Talbot and Margam which for reasons of geography can't get a signal from the Kilvey Hill transmitter across the bay at Swansea. The Mynydd Emroch transmission station is owned and operated by Arqiva. In the current age of digital television, Mynydd Emroch transmitter re-radiates the signal received off-air from Kilvey Hill about 15 km to the west. However, when it was originally built, the station was considered a relay of Carmel about 40 km to the northwest. When it came, the digital switchover process for Mynydd Emroch duplicated the timing at Kilvey Hill (Mynydd Emroch's new parent station) with the first stage taking place on Wednesday 12 August 2009 and the second stage was completed on Wednesday 9 September 2009, with the Kilvey Hill transmitter-group becoming the first in Wales to complete digital switchover. After the switchover process, analogue channels had ceased broadcasting permanently and the Freeview digital TV services were radiated at an ERP of 18 W each.〔(【引用サイトリンク】title=Freeview on Mynydd Emroch TV transmitter )〕 ==Channels listed by frequency== 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「Mynydd Emroch television relay station」の詳細全文を読む スポンサード リンク
