It is owned and operated by [Arqiva](/source/Arqiva). It includes a {{convert|305.5|m|ft|0}} high [guyed steel lattice mast](/source/Radio_masts_and_towers), which is [the tallest structure in Ireland](/source/List_of_tallest_buildings_and_structures_in_Ireland). The transmission [antennas](/source/Antenna_(radio)) surmounting the structure are contained within a fibreglass cylinder. Constructed in 1963, it came into service on 18 February of that year. ==History== It was originally commissioned by the [Independent Television Authority](/source/Independent_Television_Authority) to bring ITV signals (provided by [Ulster Television](/source/UTV_(TV_channel))) to the west of Northern Ireland, including the districts of [Derry](/source/Derry) and [Enniskillen](/source/Enniskillen) on [405-line](/source/405-line) [VHF](/source/VHF), using Channel 8 ([Band III](/source/Band_III)). The transmitter commenced full service on Monday 18 February 1963.{{Cite web|url=https://www.thebigtower.com/live/Strabane/index.htm|title=TheBigTower Strabane Transmitter|access-date=2021-09-26|archive-date=2016-04-07|archive-url=https://web.archive.org/web/20160407113008/http://www.thebigtower.com/live/Strabane/index.htm|url-status=live}} 405 line television was discontinued in the UK in 1985. When [UHF](/source/UHF) television came to Northern Ireland, main transmitters were commissioned at [Limavady](/source/Limavady) and Brougher Mountain, near [Omagh](/source/Omagh). However this left a gap in the Strabane and [Newtownstewart](/source/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 2[kW](/source/kW) [effective radiated power](/source/effective_radiated_power) was sufficient to cover a very wide area, with [coverage](/source/coverage_map) available well into [County Donegal](/source/County_Donegal). In 2001, the site was installed with a transmitter for Score Northern Ireland, a regional digital radio [multiplex](/source/Multiplexing). [Digital switchover](/source/Digital_switchover) took place in Northern Ireland in October 2012, when analogue TV transmissions from this station were replaced by digital transmissions. The [coverage](/source/coverage_map) area is approximately the same as the analogue services, and there are three digital multiplexes transmitted. ==Services listed by frequency== ===Digital radio (DAB)=== {| class="wikitable sortable" !Frequency !Block !kW !Operator |- |229.072 MHz |12D |5 |[Bauer Northern Ireland](/source/Bauer_Northern_Ireland)Radio Listeners Guide 2010 Edition |} ===Digital television until 04/09/2019=== {| class="wikitable sortable" !Frequency !UHF !kW !Operator !System |- |{{UK DVB-T|ch=39|off=pos}} |39+ |0.4 |[BBC](/source/BBC) B |[DVB-T2](/source/DVB-T2) |- |{{UK DVB-T|ch=42}} |42 |0.4 |[Digital 3&4](/source/Digital_3%264) |[DVB-T](/source/DVB-T) |- |{{UK DVB-T|ch=45}} |45 |0.4 |[BBC](/source/BBC) A |[DVB-T](/source/DVB-T) |} ===Digital television after 04/09/2019=== {| class="wikitable sortable" !Frequency !UHF !kW !Operator !System |- |{{UK DVB-T|ch=32}} |32 |0.4 |[BBC](/source/BBC) A |[DVB-T](/source/DVB-T) |- |{{UK DVB-T|ch=34}} |34 |0.4 |[Digital 3&4](/source/Digital_3%264) |[DVB-T](/source/DVB-T) |- |{{UK DVB-T|ch=35|off=pos}} |35+ |0.4 |[BBC](/source/BBC) B |[DVB-T2](/source/DVB-T2) |- |{{UK DVB-T|ch=40}} |40 |0.4 |NIMM |[DVB-T2](/source/DVB-T2) |} ===Analogue television=== {| class="wikitable sortable" !{{no2}}Frequency !{{no2}}UHF !{{no2}}kW !{{no2}}Service |- |615.25 MHz |39 |2 |[BBC One Northern Ireland](/source/BBC_One_Northern_Ireland) |- |639.25 MHz |42 |2 |[Channel 4](/source/Channel_4) |- |663.25 MHz |45 |2 |[BBC Two Northern Ireland](/source/BBC_Two_Northern_Ireland) |- |695.25 MHz |49 |2 |[UTV](/source/UTV_(TV_channel)) |} ==See also== *[List of masts](/source/List_of_masts) *[List of tallest structures in the United Kingdom](/source/List_of_tallest_structures_in_the_United_Kingdom) *[List of radio stations in the United Kingdom](/source/List_of_radio_stations_in_the_United_Kingdom) ==References== {{Reflist}} ==External links== * [http://tx.mb21.co.uk/gallery/strabane/index.php The Transmission Gallery entry for Strabane transmitting station] {{Webarchive|url=https://web.archive.org/web/20101023033247/http://tx.mb21.co.uk/gallery/strabane/index.php |date=23 October 2010 }} * [http://tx.mb21.co.uk/mapsys/anatv/strabane.php TV Coverage Map] * http://skyscraperpage.com/diagrams/?b54396 * [http://www.thebigtower.com/live/Strabane/index.htm Strabane Transmitter at thebigtower.com] {{Television transmitters in the UK}} {{Black_Mountain_VHF_405-line_Transmitter_Group}} {{Supertall}} Category:Radio masts and towers in Europe Category:Transmitter sites in Northern Ireland --- Adapted from the Wikipedia article [Strabane transmitting station](https://en.wikipedia.org/wiki/Strabane_transmitting_station) by Wikipedia contributors ([contributor history](https://en.wikipedia.org/wiki/Strabane_transmitting_station?action=history)).
