It was originally built in the 1980s as a fill-in relay for UHF analogue television covering the communities of Rhayader and St. Harmon. It consists of a 45 m self-supporting lattice steel mast standing on a hillside which is itself about 345 m above sea level. The transmissions are beamed southwest and northwest to cover its targets. The Rhayader transmission station is owned and operated by Arqiva. Rhayader transmitter re-radiates the signal received off-air from Llandrindod Wells which is itself an off-air relay of Carmel about 60 km to the southwest. When it came, the digital switchover process for Rhayader 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 20 W each.〔(【引用サイトリンク】title=Freeview on Rhayader 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「Rhayader television relay station」の詳細全文を読む スポンサード リンク
