THE EMLEY MOOR STATION is the main UHF transmitter site for most of Yorkshire and home to Arqiva's landmark concrete tower. It is also the main national operations base for the ex-NTL Broadcast division of Arqiva with the responsibility of remotely monitoring their entire UK broadcast transmitter network. The station was first opened by the Independent Television Authority (ITA) on 3 November 1956, initially transmitting ITV to Yorkshire and Lincolnshire on 405-line VHF Band III, before upgrading to UHF transmission from 1966 starting with BBC2. The site is approximately five miles north-east of the facility at Holme Moss, the main BBC FM Radio (and former BBC 405-line Band I Television) transmitter for Northern England. PRIMARY UHF SERVICE AREA |
| Emley Moor's primary transmission range is approximately forty miles in radius, mostly covering South and West Yorkshire, but also extending to borderline areas of North and East Yorkshire and some far northern parts of Lincolnshire and Nottinghamshire. OVERLAP UHF SERVICE AREA |
| Satisfactory reception of Emley Moor can be obtained across much of Northern and Central Lincolnshire and some central areas of East Yorkshire (overlapping with the Belmont transmitter) plus most of North Yorkshire (overlapping with the Bilsdale transmitter). |

| THE TOWER |
|
Completed in 1971, the 330.5-metre (1083-ft) concrete tower is the third transmission structure to occupy this site, superceding both the original 135-metre (445-ft) lattice tower (dismantled in 1966) and the replacement 385-metre (1265-ft) cylindrical mast which collapsed here on 19 March 1969. The short-lived cylindrical mast was jointly the tallest man-made structure in the UK (and Europe) along with the identical 385-metre mast which still exists at the Belmont station, albeit at reduced height since re-engineering for Digital Switchover. The concrete tower is however the tallest self-supporting structure in the UK and was awarded Grade II Listed status in 2002. As a widely-recognised landmark amongst the population it serves, the tower is still predominantly referred to as 'The Emley Moor Mast', possibly a legacy of the previous structure, even though it is easily the most far-removed from the definition of a 'mast' than any other transmitting structure in the UK. THE ROC |
| Emley Moor was formally the base of one of the four Regional Operation Centres (ROCs) established by the Independent Broadcasting Authority (IBA) between 1978 an 1981 as replacement for the original fourteen Colour Control Rooms built from 1969 onwards. However, subsequent advances in remote monitoring technology enabled the further convergence of this function into the single operations centre now based at Emley Moor, resulting in the closure of the three ROC bases at Black Hill, Croydon and St Hilary. |
