It is a relay of the Winter Hill transmitter. The antenna support structure is a 17 metre-high (56 ft-high) wooden pole situated at an elevation of {{convert|64|m|ft}}.[2] Thus, the top of the pole has an overall height of {{convert|81|m|ft}} above sea level. As of 2009, the transmitter serves approximately 3,400 homes.[1] DetailsThe relay station is located on a United Utilities bore hole site near Column Road,[2] West Kirby. The relay was not an original VHF 405-line transmitter.[3] 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.[1] Being a relay of Winter Hill, the transmitter is in the BBC North West and ITV Granada TV regions. From 4 November 2009[3] 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.[3] Transmitted servicesDigital television
