The Llanelli transmitting station is a broadcasting and telecommunications facility located on high ground north of the town of Llanelli, South Wales. It was originally built by the BBC, entering service in mid 1970〔http://www.tinsleyviaduct.com/broadcasting/june.html〕 transmitting the now-defunct 405-line VHF television system. As such, it was one of the last 405 transmitters ever built. UHF colour television was added to the mast in early 1975. Currently, the transmitter provides DVB-T digital television to the area, along with Scarlet FM radio and a single multiplex of DAB digital radio. ==Specifications and history== The site has a 30 m self-standing lattice mast erected on land that is itself about 100 m above sea level. UHF television was added to the site in early 1975,〔http://txlib.mb21.co.uk/main.php?g2_itemId=2209&g2_imageViewsIndex=3〕 launching with just the three programme services that were active at the time. S4C was added in 1982 when it launched. The 405-line VHF television service closed across the UK in 1985, but according to the BBC'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〕 Llanelli was due to close early - in the third quarter of 1982. DAB radio was added in 2010. 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「Llanelli transmitting station」の詳細全文を読む スポンサード リンク
