Winter Hill transmitting station

The Winter Hill transmitting station is a broadcasting and telecommunications site on Winter Hill, at the southern boundary of the Borough of Chorley, and above Bolton in Greater Manchester, England. It is owned and operated by Arqiva.HeightThe original mast at Winter Hill was a 450ft tower that came into service on 3 May 1956, and carried the programmes of Granada ITV and ABC TV . In 1966 services were transferred to a new higher mast erected adjacent to the original tower. The main mast structure is 309.48m tall and has a diameter of 2.75m. During the period of parallel digital and analogue transmissions, the DTT antenna attached to the top of the mast brought the overall height to 315.4m, however as part of the Digital Switchover plans, this antenna has now been removed, reducing its overall height to 309.48m. It is one of the tallest structures in the United Kingdom, the tallest being the mast at Belmont with a height of 351.5m; however, at 778.1m above sea level, Winter Hill has the highest television transmitting antenna in the United Kingdom and is higher than Gragareth, the highest hill in Lancashire.
