The Tapton Hill transmitting station (grid reference SK324870), more generally known as the Sheffield (Crosspool) transmitting station, is a broadcasting and telecommunications facility which serves Sheffield in South Yorkshire and is located on a hill in the suburb of Crosspool to the west of the city. It transmits digital television (with vertical polarisation), analogue radio (FM) and DAB digital radio. It was a relay of Emley Moor for analogue television until the signals were turned off permanently following the Digital Switchover in August 2011. The site is owned by Arqiva and its aerials are at a height of 295 metres (968 ft) above mean sea level. It also feeds the Chesterfield Transmitter with its digital television signal by means of an underground fibre optic cable.
The transmitter was originally an A group for television broadcasts, but to accommodate analogue Channel 5, as well as digital television, it became a wideband, thus any A group aerials on Sheffield were generally only able to receive MUX1 (the main BBC channels, see graph) until its reallocation in March 2010. After that date most sites wouldn't reliably pick up any of the digital channels without a wideband aerial. Following the Digital Switchover, the transmitter became a K group, although the main public service multiplexes (MUXES 1-3) are now in the original A group.
