Bilsdale transmitter

The Bilsdale transmitting station is a broadcasting and telecommunications facility, located at Bilsdale West Moor, close to Helmsley, North Yorkshire, England. It includes a guyed steel tubular mast that is primarily used for radio and television transmission. The height of the mast is 314 metres (1,030 ft) to the pinnacle. It is among the most powerful in the UK at 500 kW ERP and has recently been equipped with new aircraft warning lights, in the form of arrays of ultra bright red LEDs.

History

Bilsdale was constructed in 1971 by the BBC to bring 625-line colour television on UHF to the Tees Valley for the first time. Having added UHF TV to the existing VHF TV stations at Pontop Pike and Emley Moor, it was quickly established that a new station would be required to cover County Durham and north North Yorkshire where existing coverage was poor, and thus the new station was built.

Coverage

Coverage extends throughout the Tees Valley region, encompassing north North Yorkshire and southern County Durham. This includes Harrogate and York to the south, Filey and Whitby to the east, Middlesbrough, Stockton, Darlington, Bishop Auckland, Hartlepool, Peterlee, some areas of Seaham and some areas of Sunderland to the north, and Barnard Castle and Worton to the west.

In July 2007 it was confirmed by Ofcom that the television frequency assignment after digital switchover would be such that a wideband or group K aerial would be required for reception of all six multiplexes. However, the three public service multiplexes will still fall within the station's original analogue frequency range assignment of aerial group A.
