Golm transmitter or Sender Golm was a medium wave broadcasting facility on the area of a former Reichsarbeitsdienst officer candidate school at Kuhforter Damm in Golm near Potsdam. It entered service in 1948 as the central broadcast transmitter for Brandenburg state. Until 1979 it used a wooden lattice tower of 98 m (322 ft) height with a horizontal wooden cross on its top as its antenna support. The ends of the beams of this cross were connected with wires. From the centre of each of these horizontal wires, a vertical wire was run down to the antenna tuner which was located in a building under the feet of the tower construction. The antenna of Golm transmitter consisted therefore of 4 T-antennas connected in parallel, forming an omnidirectional antenna with a natural wavelength of 528 m. The transmitter was built from second-hand parts obtained by dismantling a site in Reichenbach, Upper Lusatia. Test transmissions were undertaken on 16 April 1948, and from 1 May 1948 the facility operated on 564 kHz. [1]
The wooden tower of Golm transmitter was not a new construction. It was built from parts of two wooden masts originally erected in 1936 at Rehmate, the location of Zehlendorf transmitter, as supports for shortwave antennas. These were (together with a third mast) the only antenna towers on this site not dismantled for war reparations following World War II. As materials for structural engineering were not easily available in the Soviet occupation zone, it was decided to dismantle this structure and re-erect it as an antenna tower at Golm, although wooden radio towers was no longer state-of-the-art.
After the demolition of the wooden radio tower of Wiederau transmitter in 1953, the tower of Golm transmitter remained the tallest wooden structure in the GDR until 1979. It was a well-known landmark of the Potsdam area. On October 25, 1979 it was demolished with explosives because of structural deterioration. It was replaced by two 51 m (167 ft) tall guyed steel lattice mast radiators. [2] One of these served as the main antenna, the other as backup.
The facility was operated by Deutsche Post. Initially, the programmes of Landessender Potsdam was broadcast, later those of Radio Wolga, Berliner Rundfunk, Berliner Welle, and Radio DDR 1 and Radio DDR 2. In 1991 the programme of Berliner Rundfunk was broadcast on 693 kHz. Transmissions ceased on 20 August 1992, and dismantlement was ordered on 20 September 1993. The guyed masts together with the other facilities were dismantled in 1993/1994. [1] The area is now covered in vegetation, only parts of the foundations of one mast remain.
The Berliner Funkturm or Funkturm Berlin is a former broadcasting tower in Berlin, Germany. Constructed between 1924 and 1926 to designs by the architect Heinrich Straumer, it was inaugurated on 3 September 1926, on the occasion of the opening of the third Große Deutsche Funkausstellung in the grounds of the Messe Berlin trade fair in the borough of Charlottenburg-Wilmersdorf. Nicknamed der lange Lulatsch, the tower is one of the best-known points of interest in the city of Berlin and, while no longer used for broadcasting purposes, it remains a protected monument.
RIAS was a radio and television station in the American Sector of Berlin during the Cold War. It was founded by the US occupational authorities after World War II in 1946 to provide the German population in and around Berlin with news and political reporting.
Sender Zehlendorf or Zehlendorf (radio) transmission facility was a radio transmission facility which was in service since 1936, when a short wave transmitter was built on the occasion of the Berlin 1936 Summer Olympics in Zehlendorf 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, had 26 different antennas at the time.
The Mühlacker Broadcasting Transmission Facility is a radio transmission facility near Mühlacker, Germany, first put into service on November 21, 1930. It uses two guyed steel tube masts as aerials and one guyed steel framework mast, which are insulated against ground. It has two transmission aerials for shortwave and one free standing steel framework tower for directional radio services. The shortwave transmitter was shut off on October 19, 2004. The medium wave transmitter was switched off in January 2012.

Kalundborg Radio was a major transmission facility for long- and mediumwave at the harbour of Kalundborg in Denmark. Longwave broadcasts on 243 kHz began on 27 August 1927 and ceased on 31 December 2023. Mediumwave broadcasts on 1062 kHz began on 1 October 1951 and ceased in June 2011.
The Transmitter Ismaning was a large radio transmitting station near Ismaning, Bavaria, Germany. It was inaugurated in 1932. From 1932 to 1934 this transmitter used a T-antenna as transmitting antenna, which was spun between two 115-metre-high free-standing wooden lattice towers, which were 240 metres apart. As this antenna had an unfavourable vertical radiation pattern, which produced much skywave resulting in a too small fading-free reception area at night, in 1934 a new antenna was installed. Therefore, one of the towers was dismantled and rebuilt on a 39-metre-high (128 ft) wooden lattice base. While this work took place, an L-Antenna was used, which was spun between the other tower and a small auxiliary wooden tower. It became defunct in 1977 and was destroyed in 1983.
The Monte Ceneri transmitter was first established as the nationwide medium-wave radio transmission station for Italian-speaking Switzerland in 1933. Located on Monte Ceneri in Ticino, it broadcast on a frequency of 558 kHz.
The Żórawina radio transmitter is a facility for FM transmission at Żórawina, south of Wrocław. It was established in 1932 as "Reichssender Breslau" and used as an antenna tower. Originally it was a 140-metre-tall free-standing lattice tower built of wood, on which a wire antenna was hung up. On the top of the tower there was an octagonal ring of bronze with a diameter of 10.6 metres for electrical lengthening of the antenna.
Deutschlandfunk is a public-broadcasting radio station in Germany, concentrating on news and current affairs. It is one of the four national radio channels produced by Deutschlandradio.
The Berliner Rundfunk (BERU) was a radio station set in East Germany. The station formerly had a political focus and discussed events in East Berlin. Nowadays, it is a commercial radio station with a classic hits music format with the name "Berliner Rundfunk 91.4".
The Trier Transmitter was a medium-wave transmitter in Trier, Germany, that went into service in 1932.
The Heilsberg transmitter was a large radio transmitting station operated by the Reichs-Rundfunk-Gesellschaft between 1930 and 1945 in the German Province of East Prussia. It was sited approximately 3 kilometres (1.9 mi) northwest of Heilsberg, on the road to Preußisch Eylau (Bagrationovsk).
Stolp radio transmitter was a broadcasting station close to Rathsdamnitz, Germany southeast of Stolp, Germany. The facility, which went in service on December 1, 1938, was designed to explore whether a reduction of fading effects could be achieved via an extended surface antenna, as well as an increase in directionality by changing the phase position of individual radiators. A group of 10 antennas arranged on a circle with 1 km diameter around a central antenna was planned. A model test consisting of a 50 m high, free-standing wooden tower supporting a vertical wire which worked as the antenna was completed.
Rundfunk der DDR was the collective designation for radio broadcasting organized by the State Broadcasting Committee in the German Democratic Republic (GDR) until German reunification in 1990.
An umbrella antenna is a capacitively top-loaded wire monopole antenna, consisting in most cases of a mast fed at the ground end, to which a number of radial wires are connected at the top, sloping downwards. One side of the feedline supplying power from the transmitter is connected to the mast, and the other side to a ground (Earthing) system of radial wires buried in the earth under the antenna. They are used as transmitting antennas below 1 MHz, in the MF, LF and particularly the VLF bands, at frequencies sufficiently low that it is impractical or infeasible to build a full size quarter-wave monopole antenna. The outer end of each radial wire, sloping down from the top of the antenna, is connected by an insulator to a supporting rope or cable anchored to the ground; the radial wires can also support the mast as guy wires. The radial wires make the antenna look like the wire frame of a giant umbrella hence the name.
The Wiederau transmitter is the oldest broadcasting facility in Saxony. It is located near Wiederau, a village which is part of the municipality of Pegau, and is used for medium-wave, FM and Television broadcasting.
Ravensburg-Horgenzell transmitter was a mediumwave broadcasting facility of Deutsche Telekom used for transmitting the program of Deutschlandfunk on the area of community Horgenzell northwest of Ravensburg in Baden-Württemberg. It was inaugurated on August 23, 1951, and used until 1959 for transmitting the radio programme of SWF with a transmission power of 40 kW on 1538 kHz.

Nauen Transmitter Station in Nauen, Havelland district, Brandenburg, Germany, is the oldest continuously operating radio transmitting installation in the world. Germany's first high power radio transmitter, it was founded on 1 April 1906 by Telefunken corporation and operated as a longwave radiotelegraphy station through World War II, and during World War I became Germany's main link with the outside world when its submarine communications cables were cut. Upgraded with shortwave transmitters in the 1920s it was Germany's most advanced long range radio station, continually upgraded with the latest equipment and serving as an experimental station for Telefunken to test new technology. At the end of World War II, invading Russian troops dismantled and removed the transmitting equipment. During the Cold War it served as the GDR's international shortwave station Radio Berlin International (RBI), and was the East Bloc's second most powerful radio station, disseminating Communist propaganda to other countries. Since German Reunification in 1991 it has been operated by Deutsche Telekom, Germany's state telecommunication service. The original 1920 transmitter building designed by architect Herman Muthesius is still used; it is one of the many remaining buildings designed by that architect that is a protected cultural heritage site.
