The Abergavenny transmitting station was originally built by the IBA in 1969 as a relay for BBC and ITV VHF 405-line analogue television. It consists of a 46 m guyed lattice mast carrying the aerials at the top. This structure was built on a 440 m hill known as Gilwern Hill overlooking the towns of Gilwern and Abergavenny in Monmouthshire, South Wales. The band III VHF television feeds were provided off-air from St. Hilary and Wenvoe, both near Cardiff. In 1973〔http://txlib.mb21.co.uk/main.php?g2_itemId=2209&g2_imageViewsIndex=3〕 the site was enhanced to transmit UHF analogue colour television. The UHF television feed came via a two-hop route from Wenvoe, via the Ebbw Vale repeater. The 405-line VHF television service closed across the UK in 1985, but according to the BBC's and IBA's transmitter list〔http://www.pembers.freeserve.co.uk/405-Lines/Transmitters.gif〕 and the BBC's internal "Eng. Inf." magazine,〔http://www.bbceng.info/Eng_Inf/EngInf_4.pdf〕 Abergavenny was due to close early - in the third quarter of 1982. Currently, the hill's transmitters provide UHF digital terrestrial TV, VHF FM radio and DAB digital radio. The transmission station is currently owned and operated by Arqiva. Freeview digital terrestrial TV was not available from this transmitter before the digital switchover process began at Wenvoe, with the first stage taking place on 31 March 2010. The second stage was completed on 27 April 2010.〔(【引用サイトリンク】title=Freeview on Abergavenny 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「Abergavenny transmitting station」の詳細全文を読む スポンサード リンク
