The Mendip transmitting station is a broadcasting and telecommunications facility on the summit of Pen Hill, part of the Mendip Hills range in Somerset, England, at 305 metres (1,001 ft) above sea level. The station is in St Cuthbert Out civil parish, approximately 2 miles (3.2 km) north-east of Wells. Its mast, 293 m (961 ft) high, was built in 1967 and is the tallest structure in South West England.

Digital terrestrial television in the United Kingdom encompasses over 100 television, radio and interactive services broadcast via the United Kingdom's terrestrial television network and receivable with a standard television set. The majority of digital terrestrial television (DTT) services, including the five former analogue channels, are broadcast free-to-air, and a further selection of encrypted pay TV services are also available. Freeview is the only DTT service since Top Up TV closed in 2013.
