THE DIVIS TRANSMITTER is the main high-power UHF and BBC National FM/DAB station that serves the counties of Armagh, Antrim and Down in Northern Ireland. Sited just outside Belfast, it is the primary UHF/FM main station in Northern Ireland and was originally the country's main BBC 405-line television transmitter, coming into operation in this capacity in July 1955. As such, it was the first permanent television transmitter to be established within Ireland. Although one of three UHF main stations in Northern Ireland, it is the only one to feature a stayed mast, the other stations at Brougher Mountain and Limavady both utilising smaller self-supporting towers. Stayed masts are however located at the UHF relay stations at Londonderry and Strabane (respectively former BBC and ITA 405-line relays) and at Black Mountain, the former ITA 405-line main station that is sited adjacent to Divis. The Divis station is located in a range of hills directly overlooking Belfast to the east, in an area which for many years was controlled by the Ministry of Defence, until it was sold in 2004 to the National Trust and subsequently opened to the public. It is sited between the peaks of Divis Mountain and Black Mountain and is ironically closer to the latter than the transmitter that is named after it. |
