Brookmans Park transmitting station

The Brookmans Park transmitting station is a facility for medium wave (MW) broadcasting at Brookmans Park, Hertfordshire, north of London (grid reference TL259050). The station was built in the 1920s by the BBC as the first of a network of regional dual ("twin wave" was the term then used) transmitter stations, replacing the city-based ones used previously, and this was to cover the Home Counties, London and South East. The station is now owned by Arqiva and transmits BBC Radio 5 Live, talkSPORT, Absolute Radio and Lyca Radio.
