Droitwich transmitter
The Droitwich transmitter is a transmission system for long and medium wave, which was put into operation in 1934 near Droitwich Spa in England . The operator is the telecommunications company Arqiva on behalf of the BBC and the private radio companies TIML Radio Limited (Absolute Radio) and UTV Radio (Talksport).
The antenna of the 400 kW transmitter, which worked at 200 kHz until 1989 and now at 198 kHz BBC Radio 4 , is a T-antenna attached to two 213 m high, braced steel truss masts that are isolated from the ground . With the transmitters in Burghead and Westerglen , it forms a single-frequency network . In addition, there are two guyed self-radiating steel framework masts in Droitwich , over which three medium-wave transmitters broadcast their programs on the frequencies 693 kHz, 1053 kHz and 1215 kHz.
The carrier oscillation of the transmitter is derived from a rubidium atomic clock located in the station building. It is therefore a calibration frequency .
