Sandy Heath is the main local TV transmitter for Bedfordshire, Cambridgeshire, Peterborough, Northamptonshire, North Hertfordshire as well as Stevenage, north Buckinghamshire (including Milton Keynes), parts of Essex (such as Saffron Walden and Harlow), parts of Suffolk (such as Newmarket and Haverhill) and parts of Leicestershire (including Market Harborough).

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

The Peterborough BBC mast opened on 5 October 1959, but had no ITV television broadcasting.

[6] In April 1964 it would be a £80,000 lattice mast, made by BICC of Preston, with all steelwork galvanised by Painter Brothers of Hereford,[7] and a transmitter from EMI Electronics.

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.

[22] Anglia was to go colour on 18 January 1971, but there was a pay dispute with the Association of Cinematograph, Television and Allied Technicians.

The Sheerhatch television relay, near Moggerhanger, began operating on Monday 20 November 1967, serving Bedford.
