Sender Zehlendorf

Sender Zehlendorf is a radio transmission facility which has. Been in service since 1936, when a short wave transmitter was built in Zehlendorf (a village near Oranienburg) as part of the establishment of permanent radio services. This Zehlendorf site, which until the end of World War II was referred to as the Rehmate Radio Transmission Centre (German:Funksendestelle Rehmate), had 26 different antennas.

In 1945, most of the Rehmate Radio Transmission Centre was dismantled by the Soviet occupying forces as reparation, who left only three wooden radio masts. These wooden masts supplied the building material for a 100-metre-tall transmission tower built at Golm in 1948, which was used until 1979.

In 1952 it was decided to build at the location of the former radio transmission center Rehmate the central long wave transmitter of the GDR. For this between 1956 and 1958 a triangle plane aerial, which was hung up on three 150 metres high guyed masts of lattice steel, which were insulated against ground was built. A second transmitting antenna, which should become the main antenna, was built between 1960 and 1962. It consisted of a 351 metres high, lattice steel framework mast, at which a conical cage aerial was mounted, making it the tallest structure in Europe between 1962 and 1964. With this antenna a transmitting power of 750 kilowatts in the long-wave rae on a frequency, which was reduced in course of the time gradually for the reduction by interference from 185 kHz to 177 kHz, was possible. The maximum transmitting power, which is possible over the triangle plane aerial, is 500 kilowatts.
