Black Hill transmitting station
From Wikipedia, the free encyclopedia
The Black Hill transmitting station is a facility for FM and TV broadcasting on Black Hill (grid reference NS828647), North Lanarkshire, Scotland near the town of Airdrie on the eastern outskirts of the Greater Glasgow metropolitan area. It has a guyed mast 306.6 metres (1006 ft) tall, bringing the antennas to a height of 540 metres above sea level. It was built in 1961 and is now operated by Arqiva.
The present mast is the second to have been built at the site. The first, built in 1957 brought the Independent Television service to Central Scotland and opened for service on 31 August 1957. Unfortunately complex anomalies in the behaviour of the antenna caused its performance to be less than predicted, and the decision was taken in 1959 to replace the mast with a higher structure and a more conventional aerial on the outside of the mast rather than inside as had been the case with the first mast. The original 750 foot mast was then dismantled and later used at the Selkirk station in the Borders where it still stands.
Between 1961 and the end of the 405 line ITV service in 1985 the Black Hill aerial had the highest effective radiated power of any transmitter in the ITV network with 475kW radiated towards Dundee.
