The Wrekin transmitting station
From Wikipedia, the free encyclopedia
The Wrekin transmitting station is a telecommunications and broadcasting facility on the The Wrekin, a hill in the county of Shropshire, England. It includes a 52-metre tall free-standing lattice tower with transmitting antennas attached at various heights. At present, it broadcasts all analogue and digital television broadcasts across 15 UHF frequencies, alongside digital and FM (analogue) radio.

[edit] Television
Like the neighbouring Granada transmitter, Winter Hill, The Wrekin serves a large chunk of North and Mid Wales, despite being the incorrect regional variation. The reason for this is because of the obvious carriage of five at same quality as channels 1-4, and also it carries the English Channel 4 as appose to the Welsh equivalent, S4C. In addition, after digital switchover, The Wrekin will carry all six multiplexes while local relays will only carry three. This is a problem, as the Welsh terrain disables many Welsh viewers from receiving DTT from nearest Welsh transmitter, Moel-y-Parc TV Mast, so the relays of the transmitter to "fill in the gaps" will only carry half the channels. Another reason the viewers of North Wales are tuned to transmitters such as The Wrekin was that Midlands ITV franchisee, ATV launched in 1956, six years before North Wales' franchise, WWN, and viewers tuned to the Wrekin immediately had two channels instead of one with Welsh transmissions.
[edit] Analogue Channels
All analogue channels (including five) are broadcast at 100k ERP, horizontal polarisation:
- UHF 26: BBC ONE West Midlands
- UHF 33: BBC TWO England
- UHF 23: ITV1 Central
- UHF 29: Channel 4
- UHF 35: five
[edit] Digital Channels
Unlike analogue television, the Wrekin has a sub-transmission site designed to serve the aast of the region, to fill areas in which the initial broadcasts fail to reach. Unlike the analogue broadcasts, the digital transmissions require a wideband aerial in order to receive multiplex C and D, which are out of the traditional aerial band. Both versions of multiplexes 1-B are broadcast at 2 kW, while multiplexes C and D are broadcast at 1 kW ERP.
- UHF 21: Multiplex 1 (BBC)
- UHF 31: Multiplex 2 (ITV / Channel 4)
- UHF 24: Multiplex A (SDN / five)
- UHF 27: Multiplex B (BBC)
- UHF 53: Multiplex C (National Grid Wireless)
- UHF 57: Multiplex D (National Grid Wireless)
also:
- UHF 39: Multiplex 1 (BBC)
- UHF 49: Multiplex 2 (ITV / Channel 4)
- UHF 42: Multiplex A (SDN / five)
- UHF 45: Multiplex B (BBC)
After digital switchover, it is expected that the frequencies serving the east of the region will be removed for compromise frequencies that has better reception in all areas of the region.
