The Stuttgart telecommunications tower is a 192.4 meter high telecommunications tower on the Frauenkopf in Stuttgart, Baden-Württemberg .

The reinforced concrete structure erected between 1969 and 1971 is internally referred to as " Radio Transmission Center Stuttgart 7" by the owner, Deutsche Funkturm (DFMG), a subsidiary of Deutsche Telekom . In contrast to the neighboring Stuttgart television tower , the telecommunications tower is not open to the public.

Geographical location

The Stuttgart telecommunications tower stands on the wooded Frauenkopf ( 462.3  m above sea  level ). It is located in the Stuttgart-Ost district between the districts of Gablenberg in the north and Frauenkopf in the east. On the southwestern neighboring Hohen Bopser stands the Stuttgart TV tower, 1.5 km away.

history

Old telecommunications tower

The old Stuttgart telecommunications tower was erected in 1954 in a four-month construction period. It was 58 meters high and initially served the directional radio traffic of the Deutsche Bundespost . By adding an antenna carrier, it reached a height of 97 meters from 1960. After the commissioning of a transmitter for the A network , the age of mobile communications began in the greater Stuttgart area. From 1961 onwards, the first television test transmissions were broadcast by the Frauenkopf, until the ZDF was switched on in regular operation on April 1, 1963. Shortly afterwards, on October 28, 1963, the Bundespost put an FM transmitter into operation for AFN . On April 5, 1969, a transmitter for the third television program of the SDR followed.

Today's telecommunications tower

Since the previous telecommunications tower no longer met the radio requirements, the architects Leonhardt, Andrä and Partner planned a successor. The type tower FMT 3 served as the basis for this . The new building was built by Siemens-Bauunion and the engineering company Wayss & Freytag . The construction costs amounted to around DM 9.5 million. The old telecommunications tower was finally demolished in 1975.

description

The Stuttgart telecommunications tower has a foundation 11.0 meters deep and a diameter of 28.0 meters. The tower shaft with a circular diameter tapers from 12.2 to 6.4 meters and rises 142.5 meters high. A 49.9 meter high metal antenna forms the end.

The tower carries an operating room with a diameter of 43 meters at a height of 33 meters. For several years now, it has been provided with a flashing light sculpture at Christmas time. The tower cage , which barely protruded over the forest, avoided expensive hanging scaffolding, so the conical bowl could be scaffolded directly from the site.

Frequencies and Programs

In addition to directional radio , mobile radio and BOS radio , the telecommunications tower is primarily used for broadcasting radio and television programs. Since May 22, 2006, digital terrestrial television programs have been broadcast from here ( DVB-T ), after the antenna tip was replaced on April 3, 2006 with the help of a helicopter. The analog broadcast of the two television programs ZDF and SWR was discontinued on July 24, 2006.
