The Freinberg Transmitter is a broadcasting transmitter on the Freinberg near Linz. It was established in 1928 as medium wave broadcasting station and used until 1936 a T-antenna, which hung up on two guyed masts, which were 45 metres tall.

Contents

In 1936, the T-antenna was replaced by a 165 metre tall mast, insulated against ground.

In summer 1950, the antenna mast was shortened to 120 metres, because it was too long for the new frequency and would have a bad radiation diagram.

In October 1957, the mast was again extended to 146 metres and in 1965 the transmitters were replaced by a new device.

At the beginning of the 1980s, medium wave broadcasting ceased at Freinberg. The mast is now used for FM transmission.

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.

<span class="mw-page-title-main">Ismaning radio transmitter</span> Architectural structure

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.

<span class="mw-page-title-main">Mainflingen transmitter</span>

The Mainflingen mediumwave transmitter is a mediumwave transmission facility south of the A3 motorway near Mainflingen, Hesse, Germany. Mainflingen was the first mediumwave transmitter for the radio station Deutschlandfunk. It went into service in 1962 with a transmission power of 50 kW, on a frequency of 1538 kHz, at the upper end of the mediumwave band. This frequency has a bad groundwave propagation and therefore a low range at daytime, but an excellent skywave propagation with a long range at night.

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.

Radio masts and towers are typically tall structures designed to support antennas for telecommunications and broadcasting, including television. There are two main types: guyed and self-supporting structures. They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them.

<span class="mw-page-title-main">RKS Liblice 2</span>

The RKS Liblice 2 are two 355 m (1,165 ft) tall guyed masts located east of Prague near Liblice, in close proximity of the RKS Liblice 1. These lattice steel towers are built 120 m (390 ft) apart from each other, what formed a slightly directional radiation pattern directed towards Spanish Madrid transmitter on the same frequency. The masts carry a special anti-fading cage aerials. Designed by Jan Šťovíček, these supertall towers currently stand as the tallest towers in the world used for broadcasting in the medium-wave range. RKS Liblice-2 was built in 1976, and is used for broadcasting on 639 kHz, with a period of inactivity from January 2022 to September 2023. During construction, two new transmitter devices of the type Tesla SRV 750 with an output power of 750 kW were installed. At first, these transmitters were switched in parallel for a transmission power of 1500 kW, after 1990 only 750 kW was used for broadcasting. Since 2023, the transmitter broadcasts with only 20 kW of power, a significant lowering. The old transmitter device was replaced with a semiconductor type TRAM one.

The Transmitter Nuremberg-Kleinreuth was a broadcasting facility for medium wave at Nuremberg, Bavaria, Germany.

<span class="mw-page-title-main">Sitkūnai Radio Station</span>

Sitkūnai Radio Station is a large facility for medium wave and shortwave broadcasting at Sitkūnai, Lithuania. The decision to build a new transmitting centre near the village of Sitkunai, about 17 km (11 mi) north of Kaunas was made by the Government of Lithuania in 1937. The building works started in 1939, and after completion, a 120 kW medium wave transmitter from Standard Telephones and Cables in the United Kingdom was ordered. However, the outbreak of World War II stopped the shipment. The empty transmitter buildings in Sitkunai survived the war with almost no damage and were used as a military compound by the German army in 1941–1944, and later as a primary school. Because the Soviet Lithuania was badly covered by radio signals, the Soviet authorities decided to continue the building work at Sitkunai and turn the site into a main shortwave and medium wave transmitting centre. During 1951 and 1952 two 50 kW shortwave transmitters, dismantled from an East German utility site as war reparations were installed in Sitkūnai. Several curtain antennas were erected and one 150 kW mediumwave transmitter was installed (665 kHz). During the January Events in 1991, Sitkūnai Radio Station was among those transmitting sites broadcasting to the world about the Soviet military actions in Vilnius when 14 civilians were killed and more than 600 injured.

Bad Dürrheim transmitter was a facility for medium wave and short wave broadcasting at 48°00'12" N and 8°31'28" E at Bad Dürrheim-Ankenbuck. It was built by the Südwestfunk in 1951 and used for mediumwave and shortwave broadcasting. Regarding the transmission antenna for mediumwave, a 120 metre tall guyed mast, which was insulated against ground was used. For the shortwave transmissions a 12 metre tall mast with a diameter of 4 metres was used. In 1962 the facility was given to German Federal Post in order to use it for transmitting the program of Deutschlandfunk. These days the shortwave transmissions of Bad Dürrheim transmitter have been moved to Bodenseesender.

The Delimara Transmitter was a relay station of Deutsche Welle near Cyclops on Malta. It was used as short- and medium wave transmission site. For the medium wave transmissions, which took place on 1557 kHz with a transmission power of 600 kW, it had two guyed masts, insulated against ground, which were guyed with polymeric guyes. The short wave antennas were mounted on free-standing lattice towers. Direction was achieved by different slewing of the various antennae available.

<span class="mw-page-title-main">Löffelstelzen radio transmitter</span> Broadcasting Facility In Germany

Löffelstelzen Transmitter is a broadcasting facility of SWR at Bad Mergentheim-Löffelstelzen in northern Baden-Württemberg, Germany. It was inaugurated at the beginning of the 1950s and used at those days a guyed mast, which was insulated against ground, because it was used for medium-wave broadcasting with a butterfly antenna for FM- and TV-transmission on its top. Later this mast was replaced by a concrete tower, which carried an antenna for FM-/TV-broadcasting on its top and a cage and a wire antenna for medium-wave broadcasting at its site. This tower was replaced between 1998 and 2000 by a 179 metre tall concrete tower. This tower is not equipped with an antenna for medium wave broadcasting, because this was ceased in 2000 at the Löffelstelzen transmission site.
