It was originally built in mid 1989〔http://www.bbceng.info/Eng_Inf/EngInf_37.pdf〕 as a fill-in relay for UHF analogue colour television covering the village of Cynwyl Elfed and the surrounding community. It consists of a 14 m self-supporting lattice steel mast standing on a hillside which is itself about 115 m above sea level. The transmissions are beamed west to cover the target. The Cynwyl Elfed transmission station is owned and operated by Arqiva. Cynwyl Elfed transmitter re-radiates the signal received off-air from Preseli about 20 km to the west. When it came, the digital switchover process for Cynwyl Elfed duplicated the timing at Preseli with the first stage taking place on 19 August 2009 and with the second stage being completed on 16 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 Cynwyl Elfed 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「Cynwyl Elfed transmitting station」の詳細全文を読む スポンサード リンク
