It includes a guyed mast with antennas attached at various heights. The mast is surmounted by a television transmitting antenna, which brings the total height of the structure to , making it the tallest structure in Wales.〔(Gwynedd Council : Track & Trace Planning Applications : Application Details )〕 It is owned and operated by Arqiva. ==History== The station was built by the ITA in the 1960s to provide a 405-line ITV Band III (VHF) TV service for north west Wales. Unlike the BBC, which served the area from Llanddona (on the island of Anglesey), Arfon gave better coverage to some areas. In October 1975 the site became a medium power UHF analogue colour television relay of Llanddona, at the time carrying BBC One, BBC Two and ITV. S4C was added in 1982. 405-line TV was finally discontinued in the UK in 1985, but it appears that Arfon's VHF transmitters were decommissioned a year early in 1984 and the transmitters themselves were reused for clinical radiotherapy. More recently, Police and Ambulance communications have been added, in addition to mobile (cellular) telephone antennas. In 1993, Classic FM began using the site for FM coverage of north west Wales in preference to Llanddona (the BBC's regional FM site), partly due to a dispute over BBC charges for sharing fees of its transmitter masts and antennas, but more because Arfon, in conjunction with Great Orme's Head (near Llandudno) gave Classic FM better coverage than the BBC sites. On 16 November 1998, local commercial radio station Champion 103 launched from studios in Bangor with its transmitter at Arfon. The mast had its aircraft warning lights replaced in Summer 2006 to red lamps employing arrays of ultrabright LEDs. On 18 July 2006, national digital radio network Digital One began broadcasting from the station. 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「Arfon transmitting station」の詳細全文を読む スポンサード リンク
