It was originally built in the 1980s as a fill-in relay for UHF analogue colour television covering the communities of Erwood, Llandeilo Graban and Llansteffan. It consists of a 20 m self-supporting lattice steel mast standing on a hillside which is itself about 215 m above sea level. The transmissions are beamed northeast and southeast to cover its targets. The Erwood transmission station is owned and operated by Arqiva. Erwood transmitter re-radiates the signal received off-air from Llandrindod Wells which is itself an off-air relay of Carmel about 40 km to the west. When it came, the digital switchover process for Erwood duplicated the timing at Carmel with the first stage taking place on 26 August 2009 and with the second stage being completed on 23 September 2009. After the switchover process, analogue channels had ceased broadcasting permanently and the Freeview digital TV services were radiated at an ERP of 2 W each.〔(【引用サイトリンク】title=Freeview on Erwood 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「Erwood transmitting station」の詳細全文を読む スポンサード リンク
