Brougher Mountain transmitting station

Brougher Mountain transmitting station is a major transmitting station in Northern Ireland. It is located between County Tyrone and County Fermanagh, on top of a 317 m (1,040 ft) high hill called Brougher Mountain. Despite being located in County Tyrone it is sometimes referred to as the "Enniskillen" or "Fermanagh" transmitter. It has four other transmitter sites in its digital television transmitter group, at Ederny, Derrygonnelly, Belcoo, and Lisbellaw. Brougher Mountain came into service on 24 February 1964, transmitting the BBC Television Service on VHF 405 lines channel B5.

It became the main UHF transmitter for the area in July 1978, when BBC One, BBC Two and UTV started transmitting in colour on the 625 line UHF service and was the last main transmitting station in the UK to be equipped for UHF. Channel 4 started transmitting from the transmitter in December 1983. Due to its close proximity to the Republic of Ireland, since the transmitter went on air in 1964, many living in counties Cavan, Monaghan, Donegal, Leitrim, Roscommon and Sligo could receive the UK channels via spill-over signals from Brougher Mountain, as well as the Strabane transmitter. During the mid-1980s Brougher Mountain was only one of three original BBC main FM transmitters in Northern Ireland affected by the frequency changes arising from the 1984 Geneva (FM) Frequency plan with all (then) three services moving up 0.5 MHz although across the border in the Republic of Ireland the RTE's FM transmitter network were more extensively affected.
