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 ...

Radio Masts And Towers
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. In the case of a mast radiator or radiating tower, the whole mast or tower is itself the transmitting antenna. Terminology The terms "mast" and "tower" are often used interchangeably. However, in structural engineering terms, a tower is a self-supporting or cantilevered structure, while a mast is held up by stays or guys. Broadcast engineers in the UK use the same terminology. A mast is a ground-based or rooftop structure that supports antennas at a height where they can satisfactorily send or receive radio waves. Typical masts are of steel lattice or tubular steel construction. Masts themselves play no part in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Towers In Spain
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, ...

Belmont Transmitting Station
The Belmont transmitting station is a broadcasting and telecommunications facility next to the B1225, one mile west of the village of Donington on Bain in the civil parish of South Willingham, near Market Rasen and Louth in Lincolnshire, England (). It is owned and operated by Arqiva. It has a guyed tubular steel mast, with a lattice upper section. The mast was shortened in April 2010 and is now in height. Before this it was high and was considered to be the tallest structure of its kind in the world (taller masts, such as the KVLY-TV mast in the United States, use steel lattice construction), the tallest structure of any type in the United Kingdom. After the top section was removed, the mast's reduced height relegated it to the second-highest in the UK after Skelton. Despite the mast being shortened it can be seen in daylight on clear days from most areas close to and within the Lincolnshire Wolds. On clear nights its bright red aircraft warning lights can be very widely s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spanish Marine Infantry
The Spanish Naval Infantry ( es, Infantería de Marina) is the Marines, naval infantry unit of the Spanish Navy () responsible for conducting amphibious warfare by utilizing naval platforms and resources. The Marine Corps is fully integrated into the Spanish Navy, Armada's structure. The Corps was formed in 1537 by Charles I of Spain (also known as Charles V, Holy Roman Emperor), making it the oldest Marines, marine corps in existence in the world, drawing from the . Mission The Spanish Marine Infantry is an elite corps, highly specialised in amphibious warfare, that is, to project an amphibious force onto a hostile, or potentially hostile, coast. Its ability to embark on a short term notice with (land, air and naval) Navy assets, makes it a unit with a high strategic value. Adding to this a high degree of training, and the capability to deploy swiftly in international waters, results in a potent dissuasive force available at a short notice in distant regions.

VLF Transmitter DHO38
The VLF transmitter DHO38 is a VLF transmitter used by the German Navy near Rhauderfehn, Saterland, Germany. It is used to transmit coded orders to submarines of the German Navy and navies of other NATO countries. DHO38 has transmitted since 1982 on 23.4 kHz with a power of up to 800 kilowatts. DHO38 uses an umbrella antenna which is carried from 8 steel tube masts with a height of 352.8 metres. Each pylon stands on 3 metre tall ceramic cylinders, which serve as insulators for voltages up to 300 kV. The masts are equipped with cylindrical oscillation Oscillation is the repetitive or periodic variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. Familiar examples of oscillation include a swinging pendulum ... dampers for better protection against storms. The transmitter is capable of transmitting signals to submarines worldwide to depths of approx. 30 metres. External links * * http://sk ...

Cartagena, Spain
Cartagena () is a Spanish city and a major naval station on the Mediterranean coast, south-eastern Iberia. As of January 2018, it has a population of 218,943 inhabitants, being the region's second-largest municipality and the country's sixth-largest non-provincial-capital city. The metropolitan area of Cartagena, known as '' Campo de Cartagena'', has a population of 409,586 inhabitants.

Submarines
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion of ...

Guardamar
Guardamar del Segura () or briefly Guardamar is a municipality of the province of Alicante located at the mouth of the river Segura in southern Valencia (autonomous community), Spain. It is a Mediterranean resort, with a large pine forest abutting an 11-km-long white sand beach. Historically an area of fishermen and farmers, Guardamar del Segura is the southernmost point where Valencian is spoken. A Phoenician colony, called ''Herna'' by Roman geographer Avienius in his book '' Ora Maritima'' was the first settlement near the mouth of Segura river, In Spanish, "guardar" means "safekeeping" and "mar" means "sea", and this is another possible basis for its current name. Guardamar is the southernmost Catalan-speaking town and in 1991 41.8% of the town's residents could speak it. Guardamar hosts local festivals like '' Moros i Cristians'', '' L'Encantà'', and ''Fogueres de Sant Joan'', which commemorate its history.
