Sahlenburg Marine Radio Station was a facility of Elbe-Weser Radio in Sahlenburg, an urban part of Cuxhaven, Germany, for marine radio service in short- and mediumwave range. Sahlenburg Marine Radio Station used first a triangular antenna, which was fixed on three guyed wooden masts, each 40 metres tall, which were erected in 1929.
In 1937 these masts were replaced by three 50-metre tall free-standing wood towers with triangular cross sections, which also carried a triangular antenna. In 1967 two of these towers were dismantled and the other was equipped with a long wire antenna.
In 1970 this tower was demolished when two 67-metre tall guyed insulated mast radiators were built. Since the shut-down of Sahlenburg Marine Radio Station, they are used for mobile phone services.
OMEGA was the first global-range radio navigation system, operated by the United States in cooperation with six partner nations. It was a hyperbolic navigation system, enabling ships and aircraft to determine their position by receiving very low frequency (VLF) radio signals in the range 10 to 14 kHz, transmitted by a global network of eight fixed terrestrial radio beacons, using a navigation receiver unit. It became operational around 1971 and was shut down in 1997 in favour of the Global Positioning System.
The KVLY-TV mast is a television-transmitting mast in Blanchard, North Dakota. It is used by Fargo station KVLY-TV and KXJB-LD's Argusville/Valley City/Mayville translator K28MA-D, along with KNGF. Completed in 1963, it was once the tallest structure in the world, and stood at 2,063 feet until 2019, when the top mount VHF antenna was removed for the FCC spectrum repack, dropping the height to 1,987 ft.
The KRDK-TV mast is a television transmitting tower in Traill County, North Dakota, United States. At 2,060 ft (630 m), it is currently the tallest structure in the United States, the second-tallest structure in the Western Hemisphere and the seventh-tallest structure in the world. It stands 72.8 ft (22.2 m) taller than the nearby KVLY-TV mast in Blanchard, North Dakota, which was previously 3.3 ft (1.0 m) taller until the removal of a VHF antenna reduced its height in 2019.
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 ananlog FM Radio and Digital-TV signals. It is located in Langenberg, Velbert, Germany and owned and operated by Westdeutscher Rundfunk, WDR.
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 Feldberg/Taunus transmitter is a facility for FM- and TV-broadcasting and for directional radio services located on the Großer Feldberg, the highest mountain in the Taunus region of Germany.
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 Arfon transmitting station is a facility for FM, DAB digital radio and television transmission near the villages of Nebo and Nasareth in Gwynedd, northwestern Wales. It includes a 308.5 m (1,012 ft) guyed mast with antennas attached at various heights. The mast is surmounted by a television transmitting antenna, which brings the total height of the structure to 317.4 m (1,041 ft), making it the tallest structure in Wales. It is owned and operated by Arqiva.
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 mast radiator is a radio mast or tower in which the metal structure itself is energized and functions as an antenna. This design, first used widely in the 1930s, is commonly used for transmitting antennas operating at low frequencies, in the LF and MF bands, in particular those used for AM radio broadcasting stations. The conductive steel mast is electrically connected to the transmitter. Its base is usually mounted on a nonconductive support to insulate it from the ground. A mast radiator is a form of monopole antenna.
The Rowridge transmitting station is a facility for FM radio and television transmission at Rowridge on the Isle of Wight in southern England.
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 Lidzbark Warmiński, on the road to Bagrationovsk.
The Lichfield transmitting station is situated close to Tamworth in Staffordshire in the West Midlands between the A5 and A51. The nearest geographical feature is Hopwas Hill. The station is owned and operated by Arqiva. The mast is known locally as Hopwas mast or Hints mast.
Eilvese transmitter was an early long-distance radiotelegraphy station at Eilvese, Germany owned by Transradio AG, used for transmission of telegrams. It went into service in 1913, exchanging commercial and diplomatic Morse code traffic on VLF frequencies with Germany's colonies, and a similar station at Tuckerton, New Jersey, USA. During World War I when the allies cut Germany's submarine telegraph cables it was one of two long-distance radiotelegraphy stations which maintained Germany's contact with the rest of the world, and was used for diplomatic negotiations between Woodrow Wilson and Kaiser Wilhelm II leading to the 1918 Armistice which ended World War I.

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.
Marnach transmitter was a broadcasting facility of RTL near Marnach in the commune of Clervaux, in northern Luxembourg. The Marnach transmitter was built in 1955 for improving the transmission of the English-speaking program on 1439 kHz, which was transmitted from 1951 with an omnidirectional antenna from Junglinster, to the British Isles and for a better transmission on this frequency to Germany at daytime. Therefore, it was given a directional antenna with a switchable directional characteristic pointing North-northeast towards the Rhine-Ruhr area, Germany's most populated area, and West-northwest in the direction of the UK. This antenna was implemented in form of a directional antenna consisting of three ground-fed 105-metre (350') tall guyed mast antennas arranged in the form of an isosceles triangle with a 90 degree angle. As transmitters, two 100 kW units switched in parallel were used when it went in service in December 1955.
