Winter Hill Mast

Tonight's run in warm sunshine went up over Winter Hill beyond the masts to the Trig Point. The mast is, probably, the main feature and is visible for miles around both day and night.

The original mast at Winter Hill was a 450 ft high tower which came into service on 3 May 1956, and carried the programmes of Granada ITV (weekdays) and ABC TV (weekends). In 1966 services were transferred to a new higher mast erected adjacent to the original tower.The main mast structure is 309.48 metres (1,015.4 ft) tall and has a diameter of 2.75 metres (9.0 ft). During the period of parallel digital and analogue transmissions, the DTT antenna attached to the top of the mast brought the overall height to 315.4 metres (1,035 ft),[1] however as part of the Digital Switchover plans, this antenna has now been removed, reducing its overall height to 309.48 metres (1,015.4 ft).[1] It is one of the tallest structures in the United Kingdom, the tallest being the mast at Belmont with a height of 351.5 metres (1,153 ft), however at 778.1 metres (2,553 ft) above sea level, Winter Hill has the highest television transmitting antenna in the UK.
