Chesterfield Transmitter
From Wikipedia, the free encyclopedia
The Chesterfield Transmitter is a television and radio transmitter which serves the town of Chesterfield in Derbyshire and surrounding areas. The transmitter is a relay of the large Emley Moor mast in South Yorkshire. The Chesterfield transmitter sits on a hillside to the north of the town, it transmits normal analogue television at 2 kW, along with digital television and radio services. It is one of the few transmitters in the UK to transmit digital television but not analogue channel, Five. Since 5 of its 6 Digital MUXES are transmitted on the same channels as Emley Moor it is not uncommon for co-channel interference to be a problem, similar problems exist with Sutton Coldfield and Waltham (see external links). The transmitter is vertically polarised as are most relays/repeaters. The altitude of the transmitting aerials is 231 metres, the actual tower being around 50m in height and of a similar design to many of the repeaters around the country. In the early 2000s an extra smaller tower was added at the side of the larger tower possibly for mobile phone use. Currently no digital radio is broadcast from this site (or anywhere in Derbyshire) but it is just possible to receive digital radio in Chesterfield from other transmitters, specifically Tapton Hill in Sheffield. The Chesterfield transmitter is owned by Arqiva (previously NTL).
