Transmitter Wavre
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. For the FM/TV/DAB transmission a free-standing lattice tower with a height of 232 metres is used. This tower whose top is guyed at four horizontal crossbars similar to Grodno TV Tower replaces the mast used for FM/TV transmissions which fell during a storm on 13 October 1983.

K08 Wavre
K, or k, is the eleventh letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''kay'' (pronounced ), plural ''kays''. The letter K usually represents the voiceless velar plosive. History The letter K comes from the Greek letter Κ (kappa), which was taken from the Semitic kaph, the symbol for an open hand. This, in turn, was likely adapted by Semitic tribes who had lived in Egypt from the hieroglyph for "hand" representing /ḏ/ in the Egyptian word for hand, ⟨ ḏ-r-t⟩ (likely pronounced in Old Egyptian). The Semites evidently assigned it the sound value instead, because their word for hand started with that sound. K was brought into the Latin alphabet with the name ''ka'' /kaː/ to differentiate it from C, named ''ce'' (pronounced /keː/) and Q, named ''qu'' and pronounced /kuː/. In the earliest Latin inscriptions, the letters C, K and Q were all us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wavre
Wavre (; ; ) is a City status in Belgium, city and Municipalities in Belgium, municipality of Wallonia, and the capital of the Provinces of Belgium, province of Walloon Brabant, Belgium. Wavre is in the Dijle, Dyle valley. Most inhabitants speak French as their mother tongue and are called "Wavriens" and "Wavriennes". The municipality consist of the following Deelgemeente, sub-municipalities: Bierges, Limal, and Wavre proper. Wavre is also called "the City of the Maca", referring to the statue of the small boy trying to climb the wall of the city hall. Tradition holds that touching the Maca's buttocks brings a year of luck. History Antiquity and Middle Ages The foundations of a wealthy Ancient Rome, Roman villa were found very close to Wavre, complete with a portico and many rooms. This part of Gaul, however, was ravaged by the Germanic peoples, Germanic invasions in the 3rd and 4th century, and it is only in the year 1050 that Wavre was mentioned for the first time, as a ...

Ground (electricity)
In electrical engineering, ground or earth may be a reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the Earth. Electrical circuits may be connected to ground for several reasons. Exposed conductive parts of electrical equipment are connected to ground to protect users from electrical shock hazards. If internal insulation fails, dangerous voltages may appear on the exposed conductive parts. Connecting exposed conductive parts to a "ground" wire which provides a low-impedance path for current to flow back to the incoming neutral (which is also connected to ground, close to the point of entry) will allow circuit breakers (or RCDs) to interrupt power supply in the event of a fault. In electric power distribution systems, a protective earth (PE) conductor is an essential part of the safety provided by the earthing system. Connection to ground also limits the build-up of static ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guyed Mast
A guyed mast is a tall thin vertical structure that depends on guy lines (diagonal tensioned cables attached to the ground or a base) for stability. The mast itself has the compressive strength to support its own weight, but does not have the shear strength to stand unsupported or bear loads. It requires guy lines to stay upright and to resist lateral (shear) forces such as wind loads. Examples include masts on sailing vessels, towers for telecommunications, meteorology, and masts on cranes, power shovels, draglines, and derricks, starting with the simple gin pole. Applications The principal applications of guyed masts are the masts of sailing vessels, guyed towers, and as the main tower of heavy equipment such as cranes, power shovels, draglines, and derricks, the simplest of which is the gin pole. Guyed masts are frequently used for radio masts and towers. The mast can either support radio antennas (for VHF, UHF and other microwave bands) mounted at its top, or th ...

Grodno TV Tower
Grodno TV Tower, also known as the Hrodna TV Tower, is a 254 metre tall lattice tower at Grodno, Belarus, built in 1984 of a unique design. The upper section of the tower is guyed using four horizontal crossbars fixed on the main body of the tower extending out from it about two-thirds of the way up the tower. Only three other towers are known to have been built of a similar design all within a three year period. They are the Wavre Transmitter, the Astara TV Tower and the Vitebsk TV Tower, the Grodno TV Tower is the tallest of the four. The Wavre Transmitter is the only one of which was built outside of the Soviet Union. Grodno TV Tower is used for FM and TV broadcasting. A nearly identical but a few metres lower tower is at Vitebsk. Transmitted programmes See also *Lattice tower A lattice tower or truss tower is a freestanding vertical latticework, framework tower.

List Of Masts
The tallest structure in the world is the Burj Khalifa skyscraper at . Listed are guyed masts (such as telecommunication masts), self-supporting towers (such as the CN Tower), skyscrapers (such as the Willis Tower), oil platforms, electricity transmission towers, and bridge support towers. This list is organized by absolute height. See History of the world's tallest structures, Tallest structures by category, and List of tallest buildings for additional information about these types of structures. Terminology Terminological and listing criteria follow Council on Tall Buildings and Urban Habitat definitions. Guyed masts are differentiated from towers – the latter not featuring any guy wires or other support structures; and buildings are differentiated from towers – the former having at least 50% of occupiable floor space although both are self-supporting structures.

Radio Masts And Towers In Europe
Radio is the technology of communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves. They can be received by other antennas connected to a radio receiver; this is the fundamental principle of radio communication. In addition to communication, radio is used for radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
