Fernmeldeturm Berlin

The Fernmeldeturm Berlin (Telecommunications Tower Berlin) is a

telecommunication tower located atop the Schäferberg hill in Berlin-Wannsee. The tower was built between 1961 and 1964, and is not open to the public. Owner and operator of the site is Deutsche Funkturm (DFMG), a subsidiary of Deutsche Telekom

.

The Fernmeldeturm Berlin is 212 metres (696 ft) tall, and its

steel-reinforced concrete shaft extends to a height of 187 metres (614 ft). Between 101 and 132 metres (331 and 433 ft) in elevation, the tower houses six floors for technical equipment. This currently consists of transmitters for DVB-T digital television, analog [|FM]] radio, and newer DAB and DMB

digital radio.

From 1964 to the early nineties, the tower was used to implement two over-the-horizon radio links to the rest of

wind loading of the comparably sized TV tower in Stuttgart

. The concrete shaft is thus 12 metres (39 ft) in diameter at the bottom, with a wall thickness of 55 centimetres (22 in). At the 97-metre (318 ft) mark, the shaft is nigh 7 metres (23 ft) in diameter.

Directly adjacent to the Fernmeldeturm Berlin is a free standing steel framework tower. Formerly it supported two 10-metre (33 ft) diameter

parabolic aerials for an over-the-horizon radio link, also to Torfhaus. These have since been removed. It is now predominantly used for cellular network

aerials.

Since 2001, the Fernmeldeturm Berlin is also used for transmissions in the medium wave range on 1485 kHz in DRM mode. Since the tower was not designed to accommodate this frequency range, a long wire aerial was installed for this purpose.
