The Mendip transmitting station is a broadcasting and telecommunications facility, situated 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 located in St Cuthbert Out civil parish in Mendip district, approximately 2 miles (3.2 km) from the centre of Wells. It includes a 281.6 metres (924 ft) tall mast, which was built in 1967 and weighs around 500 tonnes, and is the tallest structure in South West England. The mast broadcasts digital television, FM analogue radio and DAB digital radio, and had broadcast analogue colour television from 1967 until 2010.
Until 2008 a GRP aerial cylinder, which contains the analogue television transmitting antennas, was located at the top of the mast, bringing the total height of the structure to 305 metres (1,001 ft). With a mean height of 596 metres (1,955 ft) above sea level, the analogue television antennas were amongst the highest in the UK. The analogue television antennas were removed in 2010, the original antenna cylinder being replaced with a new antenna assembly, ready for digital switchover in 2010. The new assembly is slightly shorter than the previous cylinder causing the overall mast height to be reduced from 305 metres (1,001 ft) to 293 metres (961 ft).
There are red aircraft warning lamps (six sets of two lights) up the mast with two lights on top. The lights were upgraded in February 2007 to comply with CAA 2000 Air Navigation Order, designed to prevent low flying aircraft from hitting the mast.
