Stirling Transmitting Station is a transmission facility on Earls Hill southwest of Stirling. It was built at the end of the 1950s for the radio navigation system Dectra with a 183 metres ( 600 ft) tall guyed mast radiator, which was used after shut-down of Dectra as a Decca transmitter. Today the facility is used for cell phone transmitters.
