The Heathfield transmitting station is a facility for FM and television transmission 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.

The transmitter broadcasts television and radio services to East Sussex and parts of West Sussex. This includes towns such as Hastings, Eastbourne, Bexhill, St Leonards-on-Sea, Heathfield, Lewes, Uckfield, Seaford, Newhaven, Peacehaven, Crowborough, Hailsham, Haywards Heath, Burgess Hill and East Grinstead.

Along with Bluebell Hill, Dover and Whitehawk Hill, Heathfield transmits regional television services from BBC One South East and ITV Meridian (east).

Heathfield has 13 local relays: Bexhill, Ham Street, Haywards Heath, Hollington Park, East Dean, Eastbourne, Eastbourne (Old Town), Lamberhurst, Lewes, Mountfield, Newhaven, Sedlescombe and Wye.
