Wrexham-Rhos transmitting station

The Wrexham-Rhos transmitting station is a digital television relay of Moel-y-Parc, and forms part of the Wales television region. Despite its name, the station is situated in Moss Village and serves the town of Wrexham, the northern area of Wrexham County Borough and south-western Flintshire. It is a free-standing lattice tower structure serving around 85,000 homes which are unable to receive broadcasts from Moel-y-Parc due to Hope Mountain.

This area is traditionally served by English transmitters at Winter Hill and The Wrekin, which have historically provided English-language channels Channel 4 and Channel 5, plus the digital terrestrial services ONdigital/ITV Digital (from 1998 to 2002) and Freeview from 2002 onwards. Wrexham-Rhos was constructed to coincide with the 1977 National Eisteddfod in Wrexham, initially providing S4C and BBC One Wales,[1] later joined by HTV Wales in 1997 and BBC Two Wales in 1999.[2]

Prior to analogue switch-off, Wrexham-Rhos broadcast four of the five national terrestrial stations. Channels 1 to 3 were broadcast at 200 W ERP, while S4C was broadcast at 400 W. In 1998, due to the upcoming launch of ONdigital from neighbouring transmission site, Winter Hill, S4C from the relay was required to change frequency (from UHF Channel 67) two years later. A message was displayed telling viewers to re-tune their televisions of the channel were carried for a couple of months. When the original frequency was switched off, the power on the newer version was increased.
