There are three Redruth transmitting stations:

Redruth (Four Lanes)

A broadcasting and telecommunications facility in west Cornwall (grid reference SW690395, 50°12′35″N 5°14′19″W / 50.20972°N 5.23861°W / 50.20972; -5.23861). It includes a 152.4 metres (500 ft) high guyed steel lattice mast with square cross section, which is surmounted by the television transmitting antennas, bringing the overall height of the structure to 173 metres (568 ft).^[1] It is owned and operated by Arqiva. It transmits DVB television, FM radio and DAB radio (and previously, UHF Analogue television signals). It is sometimes referred to as Four Lanes, because of the proximity of the mast to neighbouring village of the same name. The main mast is lit with four bright red aircraft warning lights, a statutory requirement of the Civil Aviation Authority.

This transmitter provides coverage to West Cornwall and the Isles of Scilly.

A broadcasting transmitter at Lanner Hill (grid reference SW709403, 50°13′4″N 5°12′45″W / 50.21778°N 5.21250°W / 50.21778; -5.21250). It transmits mediumwave radio signals. It was built in 1942 by German POWs. It is sometimes referred to as Redruth MF, short for Redruth Medium Frequency (Medium Wave). It is owned and run by Arqiva.

A microwave transmitting tower located on the hill, Carnmenellis, 2 miles (3.2 km) south of Redruth. It is owned and run by BT.
