HWU Transmitter
The HWU transmitter is a French facility for transmitting orders to submerged submarines of the French Navy. Situated near Rosnay at 46°42'47"N, 1°14'39"E, it is one of the largest radio transmitters in France and is visible on satellite pictures although it is completely blurred out. It uses an antenna carried bthirteen guyed masts(the tallest one 357 m, 6 of 310 m, 6 of 270 m), which are, together with the masts of the Allouis longwave transmitter, the tallest structures in France. The HWU transmitter works on 18.3 kHz, 20.9 kHz and 21.7 kHz. Its transmissions can be easily received in Europe when the transmitters are active by using a PC soundcard connected to a receiving coil and FFT software. Although the signals are very easy to receive, it may be impossible to decipher them without knowing the cipher and key used in the communications.

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 List of tallest buildings and structures, List of tallest freestanding structures and List of tallest buildings and List of tallest towers 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.

Towers In France
A tower is a tall structure, taller than it is wide, often by a significant factor. Towers are distinguished from masts by their lack of guy-wires and are therefore, along with tall buildings, self-supporting structures. Towers are specifically distinguished from buildings in that they are built not to be habitable but to serve other functions using the height of the tower. For example, the height of a clock tower improves the visibility of the clock, and the height of a tower in a fortified building such as a castle increases the visibility of the surroundings for defensive purposes. Towers may also be built for observation, leisure, or telecommunication purposes. A tower can stand alone or be supported by adjacent buildings, or it may be a feature on top of a larger structure or building. Etymology Old English ''torr'' is from Latin ''turris'' via Old French ''tor''. The Latin term together with Greek τύρσις was loaned from a pre-Indo-European Mediterranean language, ...

Military Radio Systems
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anthorn Radio Station
Anthorn Radio Station is a naval and government radio transmitting station located near Anthorn, Cumbria, England, overlooking the Solway Firth, and is operated by Babcock International (with whom former operators VT Communications are now merged). It has three transmitters: one VLF; one LF; and an eLORAN transmitter. It is on the site of the World War II military airfield which was operated by the Fleet Air Arm as HMS ''Nuthatch''. RNAS Anthorn John Laing & Son began building an airfield at Anthorn for the Fleet Air Arm in late 1943, and Royal Naval Air Station, Anthorn, was commissioned as HMS ''Nuthatch'' on 7 September 1944, with three tarmacadam runways. It was the base of No. 1 Aircraft Receipt and Despatch Unit (No. 1 ARDU), which had the job of receiving aircraft fresh from manufacturers, modifying them to Service standards and despatching them to operational squadrons, with the unit specialising in the Vought F4U Corsair, Supermarine Seafire, Fairey Barracuda and ...

Torreta De Guardamar
Torreta de Guardamar (, ) or Torre de los Americanos is a 380-metre tall guyed mast, guyed radio mast erected by the US Navy near Guardamar del Segura, Spain. It was built in 1962 and is the tallest architectural structure in both the Iberian peninsula and the European Union, and the tallest military structure in Europe. Its base is situated 64 metres above sea level at a distance of 1.4 km from the sea. Details Torreta de Guardamar is a mast radiator insulated from earth, and is used to transmit orders to submerged submarines. It is made as a lattice structure with triangular cross section. In spite of its enormous height, it is low in relation to the wavelength of the waves it transmits. Its capacity is augmented by multiple cables connected to its top and running to anchors around the mast. These cables are electrically connected to the mast and are divided at a certain distance by insulators. The transmitter using Torreta de Guardamar as antenna had been, since its inaug ...

Sainte-Assise Transmitter
The Sainte-Assise transmitter (french: Émetteur de Sainte-Assise) is a very low frequency (VLF) radio transmitter and military installation located on the grounds of the in the communes of Seine-Port, Boissise-la-Bertrand, and Cesson in the Seine-et-Marne department of the Île-de-France region of France. The transmitter's original equipment was inaugurated on 9 January 1921, at the time being the most powerful radio transmitter on Earth. On 26 November 1921 the first French radio program was transmitted from Sainte-Assise. In 1965 the transmitter was used to send VLF signals to FR-1, the first French satellite. Since 1998 the French Navy has used the transmitter to communicate with submerged submarines. Design The original equipment of the Saint-Assise transmitter included large spiral "pancake" inductors in a high-power longwave alternator transmitter which served as a transatlantic wireless telegraphy station. These combinations of inductors and alternator transmitters w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
