A transmission tower is a tall structure, usually a lattice tower made of steel that is used to support an overhead power line. In electrical grids, transmission towers carry high-voltage transmission lines that transport bulk electric power from generating stations to electrical substations, from which electricity is delivered to end consumers; moreover, utility poles are used to support lower-voltage sub-transmission and distribution lines that transport electricity from substations to electricity customers.
The Longwave transmitter Solec Kujawski is a longwave broadcasting facility of Polskie Radio for the AM-LW (longwave) 225 kHz frequency/1333 meters wavelength. Its construction was necessitated by the collapse of the Warsaw radio mast on 8 August 1991 and the resistance of the local population to its reconstruction. Tower Height 948 feet/289 meters and 1080 feet/330 meters. Height above sea level 209 feet/64 meters MSL.
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 Eifel Transmitter is an FM and TV transmission facility for the German broadcasting company of SWR and is located on the Scharteberg near Kirchweiler, Germany. Until 1985, the Scharteberg transmitter used a 160 metre tall guyed mast. However this mast did not allow good reception in deep valleys, so in 1985 a new, 302 metre tall, guyed, steel framework mast was built, becoming the tallest structure of Rhineland-Palatinate. The elements of this mast were built by the firm of Hein, Lehmann AG, whilst construction work was carried out by BBS AG, Ludwigshafen. The first 20 metres of the mast were built using a small crane. The mast elements in heights between 20 and 100 metres were mounted by the aid of a car crane, while for the sections above a derrick crane was used. The new mast of Scharteberg transmitter consists of a 288 metre tall, guyed, lattice, steel structure with a square cross section, a side length of 2.1 metres and a 14 metre long GFK-cylinder on top for the UHF antenna. The total weight of the structure is 204 tons. The mast is guyed at 4 levels, 57, 123, 195 and 273 metres above ground. It is equipped with an elevator which runs up to a height of 281 metres. For aircraft warning 20 red neon lamps and two blinking lights with 1000 watt lamps are installed.
The Sottens Transmitter is the nationwide transmitter for French-speaking Switzerland. The transmitter is located at Sottens, Canton of Vaud, Switzerland. It is run on 765 kHz with a power of 600 kilowatts and is easily receivable during the night throughout the whole of Europe. Since 1989 the aerial used has been a centre-fed dipole fixed on the outside of a 188-metre-high grounded freestanding steel framework tower. Before 1989 a 190-metre high self-radiating, free standing steel framework tower was used as a transmission aerial. The Sottens transmitter most recently broadcast the Option Musique radio programme from Radio Suisse Romande, up until 5 December 2010.
A lattice tower or truss tower is a freestanding vertical framework tower. This construction is widely used in transmission towers carrying high voltage electric power lines, in radio masts and towers and in observation towers. Its advantage is good shear strength at a much lower weight than a tower of solid construction would have as well as lower wind resistance. In structural engineering the term lattice tower is used for a freestanding structure, while a lattice mast is a guyed mast supported by guy lines. Lattices of triangular (3-sided) cross-section are most common, particularly in North America. Square (4-sided) lattices are also widely used and are most common in Eurasia. Lattice towers are often designed as either a space frame or a hyperboloid structure.
The Blaw-Knox company was an American manufacturer of steel structures and construction equipment based in Pittsburgh, Pennsylvania. The company is today best known for its radio towers, most of which were constructed during the 1930s in the United States. Although Blaw-Knox built many kinds of towers, the term Blaw-Knox tower usually refers to the company's unusual "diamond cantilever" design, which is stabilized by guy wires attached only at the vertical center of the mast, where its cross-section is widest. During the 1930s AM radio broadcasting stations adopted single mast radiator antennas, and the Blaw-Knox design was the first type used. A 1942 advertisement claims that 70% of all radio towers in the United States at the time were built by Blaw-Knox.
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.
The Wavre radio transmitter is a facility for Fm, Dab+ and TV broadcasting near Wavre in Belgium. Formerly the mediumwave transmissions used a grounded 250-metre-high guyed mast. Furthermore, there was a backup mast for medium wave transmissions, which was 90 metres high. For shortwave broadcasting there were several directional antennas and a curtain antenna.
The Croydon transmitting station is a broadcasting and telecommunications facility on Beaulieu Heights in Upper Norwood, London, England, in the London Borough of Croydon, owned by Arqiva. It was established in 1955 and initially used a small lattice tower. The present tower is 152 metres (499 ft) high and was built in 1962.
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.
The Tacolneston transmitting station is a facility for both analogue and digital VHF/FM radio and UHF television transmission near Tacolneston, 11 miles (18 km) south-west of Norwich, Norfolk, England.
Purdown BT Tower, also known as Purdown Transmitter, is a 70.1 metres (230 ft) tall telecommunications tower in Bristol, England. Built in 1970 for the British Telecom microwave network, it is now used to transmit radio and provide mobile phone coverage.
The Nordkirchen transmitter was a medium-wave broadcasting facility of Media Broadcast and former Deutsche Telekom near Nordkirchen in Northrhine-Westphalia, Germany. It was built in 1979 and 1980 after and finaly de-funct in 2018.
The Turner Broadcasting tower was a 314.3-meter (1,031 ft) free-standing lattice tower in Atlanta, Georgia. It was located next to the Downtown Connector between Spring, West Peachtree, 10th and 12th Streets in Midtown. The tower had a triangular cross-section and was built on the site of a previous four-sided broadcast tower built for WAGA-TV 5 and to serve WJRJ-TV which was founded by Rice Broadcasting Inc. which was owned by a local Atlanta entrepreneur, Jack M. Rice, Jr. It is the tallest freestanding structure to ever be voluntarily removed in the United States and third tallest in the world.
The Blaenplwyf transmitting station is a broadcasting and telecommunications facility located near the village of Blaenplwyf about 10 kilometres (6 mi) to the south west of the town of Aberystwyth, in Ceredigion, Wales. It was originally built by the BBC, entering service in October 1956 acting as a main transmitter for BBC Band II VHF FM radio.
Vitebsk Television Tower, also known as Viciebsk, Vitsebsk or Vitsyebsk TV Tower, is a 244 m (801 ft) tall steel Belarusian lattice television tower that is located in the city of Vitebsk, in Belarus, thus the name. Having been built in 1983 as a unique, multi-purpose television tower, the Vitebsk TV Tower is utilized for transmitting FM-/TV-broadcasting throughout the city.
