Huntshaw Cross transmitting station is a telecommunications facility serving North Devon including the towns of Barnstaple and South Molton. It broadcasts television, radio and mobile telephone services and is currently owned by Arqiva. It is located on the B3232 road at Huntshaw, Great Torrington. Grid reference SS527220. The mast is 164 metres (538 ft) high.

The site was opened by the Independent Television Authority on 22 April 1968 carrying the ITV programmes of Westward Television using the now defunct 405 line VHF transmission system. In this context, the site was treated as an off-air relay of Stockland Hill.

625 line UHF colour TV transmissions commenced on 5 November 1973. The high power output of the UHF station and its location allowed its signal to be received clearly in parts of south Wales. It became a popular station from which to receive network programmes from the BBC South West and ITV Westward/TSW regions, as well as Channel 4 which was not broadcast on Welsh transmitters. Evidence of this can easily be seen in Swansea (for instance) where many Group C/D TV aerials can be seen pointing south, across the water.

The 405-line transmissions from Huntshaw Cross were discontinued in the 2nd quarter of 1983, somewhat before the final UK-wide shutdown of the VHF system in January 1985.

Digital switchover began at the site in the early hours of 1 July 2009 when the BBC Two analogue service was switched off just after 01:20 BST. Switchover was completed in the early hours of 29 July 2009 with the analogue services disappearing one by one, starting with BBC One at a few seconds after 01:30. Viewers were required to perform another retune on 30 September 2009 as SDN, Arqiva A and Arqiva B reached their final frequency positions. Final post-DSO power levels were not reached by all multiplexes on this station until March 2012.

Freeview HD became available to viewers using this site from 24 September 2010.

A local DAB multiplex for North Devon began transmitting on 2 February 2012 ahead of full launch on 6 February 2012, the local DAB service is an exact mirror of the DAB service for Exeter and Torbay.
