The Fernmeldeturm Berlin (Telecommunication Tower Berlin) is a telecommunication tower on the Schaefer mountain in Berlin-Wannsee. The Fernmeldeturm Berlin was built between 1961 and 1964 and is normally not open for visitors.
The Fernmeldeturm Berlin is 212 metres high, from which the shaft has a height of 187 metres. In a height of 101.6 metres and 132.44 metres the tower has floors for technical equipment. In these floors are mainly devices for directional radio services. From 1964 to the early nineties, the tower was used for the realisation of an overhorizon-directional radio link toward the old federal republic of Germany (Counterparts at Torfaus and Clenze). Therefore the tower was equipped with two parabolic dishes with a diameter of 30 metres, which were mounted on the shaft of the tower. These aerials were removed in 1996. Because of these aerials, the Fernmeldeturm Berlin had to be designed to stand a much higher wind pressure than the TV towers at Dortmund and Stuttgart, which are of similar height. The Fernmeldeturm Berlin was also used for broadcasting FM-radio and TV-programmes.
Close to the Fernmeldeturm Berlin there is a free standing steel framework tower, which also carried parabolic aerials for the overhorizon-link to former Western Germany.
Sinnce 2001 the Fernmeldeturm Berlin is also used for transmissions in the medium wave range on 1485 kHz in the DRM-mode. Because there are no transmission aerials for this frequency range on the site of the Fernmeldeturm Berlin, a long wire aerial was installed for this purpose.
The Fernmeldeturm Berlin-Schäferberg erected from 1961 to 1964 is a telecommunication Tower and closed to the public.
The Fernmeldeturm Berlin-Schäferberg is 212 m (695 ft) high, the shaft alone is 187 m (613 ft).
In the time from 1964 until the early 1990s this telecommunications tower was mainly used for trans-horizon relay transmissions to west germany with the counter-stations Torfhaus in the Harz and Clenze in the Lüneburger Heide.
Berlin itself is one of Europe 's younger cities, with its origin in the 12th century.
Although it was the residence of the Prussian kings, Berlin's population did not greatly expand until the 19th century, mainly after becoming the capital of the German Empire in 1871.
Berlin was devastated by bombing raids during World War II, and many of the old buildings that escaped the bombs were eradicated in the 1950s and 1960s in both West and East.
