When UHF television came to Northern Ireland, main transmitters were commissioned at Limavady and Brougher Mountain, near Omagh. However this left a gap in the Strabane and Newtownstewart areas, so in July 1977 UHF television was added to the Strabane site. Due to the elevation of the antennas (584 m above sea level), a 2kWeffective radiated power was sufficient to cover a very wide area, with coverage available well into County Donegal.
In 2001, the site was installed with a transmitter for Score Northern Ireland, a regional digital radio multiplex.
Digital switchover took place in Northern Ireland in October 2012, when analogue TV transmissions from this station were replaced by digital transmissions. The coverage area is approximately the same as the analogue services, and there are three digital multiplexes transmitted.
