It is a K group or wideband TV transmitter (horizontal polarization), though an original A group aerial will still receive four of the main six muxes,^[1] in fact from Feb 2020 only MUX 4 (SDN) was out of the A group. During DSO, the digital transmission power for the PSB and commercial muxes increased from 20 kW to 180 kW and 170 kW respectively.

Sandy Heath is the main local TV transmitter for Bedfordshire, Cambridgeshire, Peterborough, Northamptonshire, north Hertfordshire, north Buckinghamshire (including Milton Keynes) and parts of North West Essex and South West Suffolk.

Sandy Heath has 3 relay stations which are located in Northampton, ^[2] Kimpton, ^[3] and Luton. ^[4]

It also broadcasts the BBC local radio station BBC Three Counties Radio and the independent radio station Heart East, formerly Chiltern Radio.

It was opened on 5 July 1965 by Charles Hill, Baron Hill of Luton for the ITA (Anglia TV). By the end of 1965, it was hoped that nine ITA transmitters would be open.

From its start until late 1966, the transmitter could not broadcast schools programmes in the morning because the frequency (waveband) clashed with the Mullard Radio Astronomy Observatory in nearby Cambridgeshire. Anglia TV broadcast on channel 6 from noon to midnight, and the astronomy observatory operated on these frequencies during the morning.^{[citation needed]}
