The Heathfield transmitting station is a facility for FM and televisiontransmission at Heathfield, East Sussex, UK (grid reference TQ566220). Opened in 1969, its antenna mast is a 135 m (443 ft) tall guyed structure, giving the transmitter a height of 256 m (840 ft) above sea level. A Group B (or wideband or K group) horizontally polarised aerial is required to receive digital TV signals. The original analogue signals were in the Group C/D band, but all the digital MUXES should still be receivable on a C/D group aerial in reasonable signal areas (see graph).
The station's coverage area suffers from co-channel interference problems, particularly to the south, not only with Brighton (Whitehawk Hill) but with the continent as well. It is owned and operated by Arqiva.
