The Caldbeck transmitting station is a broadcasting and telecommunications facility, situated close to the village of Caldbeck, in Cumbria, England (Grid Reference: NY299425). It is owned and operated by Arqiva.

It includes a convert|337|m|ft high guyed steel lattice mast, which is the third highest structure in the United Kingdom. The transmission antennas surmounting the structure are contained within a fibreglass cylinder.

History

The station was originally commissioned by the Independent Television Authority to bring ITV signals (provided by Border Television) to Northern Cumbria and South West Scotland, including Carlisle and Dumfries on 405-line VHF, using Channel 11 (Band III). Constructed in 1961, it originally included a convert|306.6|m|ft tall guyed steel lattice mast that came into service on 1 September of that year. The BBC's VHF television and radio services were carried by the nearby Sandale transmitting station. 405 line television was discontinued in the UK in 1985.

When UHF television started in the UK in 1969, Caldbeck was selected to carry all the UHF services for the area. The original three channel line-up came into service in September 1971. Channel 4 began from Caldbeck from its launch in November 1982.

In 1993, CFM Radio launched from Caldbeck on 96.4 MHz FM, and later in 2001 the national digital multiplex Digital One entered service.

Digital Switch Over

Caldbeck is set to be one of the first transmitters in the UK to be upgraded to high power digital only TV broadcasting. At this time, the analogue signal will be permanently switched off. The process is known as Digital Switchover and is scheduled for June 2009.

Caldbeck is currently undergoing major engineering work to accommodate the new transmitters and aerials. The work entails complete replacement of the existing mast with a brand new 337 metre mast, work on which began on 26 April, 2007. Construction of the new mast structure was completed at the beginning of March 2008. [ [http://www.newsandstar.co.uk/news/1.52321 News & Star ] ] Once installation of the transmitting aerials on the new mast is complete, the old one will be dismantled.

Other masts that will require engineering work include Black Hill, (Lanarkshire) which will also need a replacement mast, and Wenvoe (Glamorgan), Sandy Heath, (Bedfordshire) and Divis (Northern Ireland), all of which will require mechanical strengthening.
