In radio, longwave, long wave or long-wave, and commonly abbreviated LW, refers to parts of the radio spectrum with wavelengths longer than what was originally called the medium-wave broadcasting band. The term is historic, dating from the early 20th century, when the radio spectrum was considered to consist of longwave (LW), medium-wave (MW), and short-wave (SW) radio bands. Most modern radio systems and devices use wavelengths which would then have been considered 'ultra-short'.
The Gleiwitz incident was a false flag attack on the radio station Sender Gleiwitz in Gleiwitz staged by Nazi Germany on the night of 31 August 1939. Along with some two dozen similar incidents, the attack was manufactured by Germany as a casus belli to justify the invasion of Poland. Prior to the invasion, Adolf Hitler gave a radio address condemning the acts and announcing German plans to attack Poland, which began the next morning. Despite the German government using the attack as a justification to go to war with Poland, the Gleiwitz assailants were not Polish but were German SS officers wearing Polish uniforms.
The Warsaw Radio Mast was a radio mast located near Gąbin, Poland, and was the world's tallest structure at 2,120 ft from 1974 until its collapse on 8 August 1991. The mast was designed for extreme height in order to broadcast Communist propaganda around the world, including to the remotest areas such as Antarctica. As of 2023, it was the third-tallest manmade structure ever built, after the Burj Khalifa tower in the United Arab Emirates in 2009, and Merdeka 118 tower in Malaysia in 2022.
The Fernmeldeturm Nürnberg, the tallest structure in Bavaria, is a telecommunication tower in Nuremberg, southern Germany. Also called the Nürnberger Ei because of its egg-shaped tower basket in a height of 185 metres, it is 292 metres high and was built between 1977 and 1980 according to blueprints by architect Erwin Heinle.
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 longwave transmitter Raszyn is a longwave broadcasting transmitter near Raszyn, Poland. It was built in 1931 and rebuilt in 1949. The designer of the mast is unknown. It has been claimed that the rebuilt tower consists of sections from the radio mast of former Deutschlandsender Herzberg/Elster; however, there is no proof of this theory. The mast of the Raszyn longwave transmitter was, at inauguration, the second-tallest man-made structure on earth and until 1962, with a height of 335 metres, the tallest structure in Europe. The tower's height is 1,099 feet.
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.
The Langenberg transmission tower is a broadcasting station for analog FM Radio and Digital-TV signals. It is located in Langenberg, Velbert, Germany and owned and operated by Westdeutscher Rundfunk, WDR.
The Orfordness transmitting station was a major radio broadcasting facility at Orford Ness on the Suffolk coast in the United Kingdom able to broadcast to much of Europe. It closed in May 2012 after more than 30 years of service. In 2017 Radio Caroline started broadcasting from the site, though not with the same intended coverage of an audience in Europe as the original station.
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.
A broadcast transmitter is an electronic device which radiates radio waves modulated with information content intended to be received by the general public. Examples are a radio broadcasting transmitter which transmits audio (sound) to broadcast radio receivers (radios) owned by the public, or a television transmitter, which transmits moving images (video) to television receivers (televisions). The term often includes the antenna which radiates the radio waves, and the building and facilities associated with the transmitter. A broadcasting station consists of a broadcast transmitter along with the production studio which originates the broadcasts. Broadcast transmitters must be licensed by governments, and are restricted to specific frequencies and power levels. Each transmitter is assigned a unique identifier consisting of a string of letters and numbers called a callsign, which must be used in all broadcasts.
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 Vakarel Transmitter was a large broadcasting facility for long- and medium wave near Vakarel, Bulgaria. The Vakarel Transmitter was inaugurated in 1937. It had one directional antenna consisting of three guyed masts and another consisting of two masts.
New Zealand Masts and Towers range in size from short flagpoles to high radio transmitter antenna structures. The highest mast is in Titahi Bay, being the highest structure in the Southern Hemisphere at time of construction. Later it became the highest in New Zealand and then later second to the Sky Tower in Auckland.
The Eiðar longwave transmitter was a facility previously used by RÚV for longwave radio broadcasting on 207 kHz with a power of 100 kW. The transmitter was situated at Eiðar near Egilsstaðir in East Iceland. It was demolished in March 2023. At the time of its closure, it used an omnidirectional aerial in the form of a 221-metre (725 ft) tall steel lattice mast radiator insulated against the ground. The transmission site was in use from 1938 until its closure in 2023.
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.
Warszewo transmitter is a radio broadcasting facility at Warszewo, Szczecin, a suburb of Szczecin, Poland.
PCJJ was a pioneering shortwave radio station in the Netherlands operated by Philips Radio on behalf of Philips Laboratories, a division of Philips Electronics. It was the first shortwave radio station in Europe, and the first dedicated shortwave radio station in the world - previous stations had simulcast AM/medium wave broadcasts.
