Dortmund-Dorstfeld transmitter
The Dortmund-Dorstfeld transmitter was a temporary mediumwave broadcasting facility at the Dorstfeld coal pit in Dortmund, Germany. The Dortmund-Dorstfeld transmitter was inaugurated on September 18, 1925. It was a T-type antenna with two wires, which was spun between two 33-metres-tall wooden guyed masts, placed in a distance of 35 metres. The facility was shut down on December 15, 1927, after the Langenberg transmitter took over. Literature.
