THE MOEL-Y-PARC TRANSMITTER is the UHF main station that serves the north-eastern sector of Wales. It is located on a remote and highly elevated site in the Clwydian Mountain Range. The station is also the main Arqiva Service Centre base in North Wales. |
|
|
|
UHF SERVICE AREA |
|
The principal service area of this transmitter covers a radius of between just 15-20 miles. Locations within this area include Flint, Holywell, Mold, Denbigh and Wrexham, as well as Prestatyn, Rhyl and Colwyn Bay on the North Wales coastline. |
|
|
|
UHF OVERLAP |
|
Due mainly to the high elevation of the transmission site, signals from this station overlap significantly towards the east and north-east into the principal service area of the Winter Hill transmitter, producing an actual transmission radius of 50-60 miles and reaching a considerably greater number of viewers than present within it's intended service area. This duplication of coverage is reciprocated by the Winter Hill transmitter which provides a viable alternative to viewers in lower-lying parts of North Wales where reception of Moel-y-Parc is difficult.

| BRIEF STATION HISTORY |
| Moel-y-Parc was opened by the Independent Television Authority (ITA) on 28 January 1963 and was the third and last of their main 405-line Band III transmitters in Wales. The station transmitted on VHF Channel 11, operating alongside the ITA's other main 405-line transmitters at St Hilary and Presely. The BBC also used this station, along with Winter Hill and Belmont, to establish one of their later generation of BBC1 405-line transmitters operating on VHF Band III. This came into service on 28 October 1965 and operated on VHF Channel 6. Regular UHF transmission from this site commenced 5 July 1969 with the opening of the BBC2 transmitter on Channel 45. |
