The transmitting mast is located on a United Utilities bore hole site near Column Road[3], West Kirby. The relay was not an original VHF 405-line transmitter.[1] For 625-line analogue services on UHF, the relay covers a geographical Winter Hill blind spot in the vicinity of West Kirby near the Dee estuary. Prior to switchover, analogue channels BBC One, BBC Two, ITV1 and Channel 4 are radiated from the site.[2]. Being a relay of Winter Hill, the transmitter is in the BBC North West and ITV Granada TV regions.
From 4 November 2009[1] some digital TV services started broadcasting from the transmitter.
The final digital switchover date was 2 December 2009, after which three digital multiplexes (known as Freeview Lite[4]) were made available.
All TV transmissions from the West Kirby site are vertically polarised.[1]
