Emley Moor Transmitting Station
The Emley Moor transmitting station is a telecommunications and broadcasting facility on Emley Moor, west of the village centre of Emley, in Huddersfield, West Yorkshire, England. It is made up of a concrete tower and apparatus that began to transmit in 1971. It is protected under UK law as a Grade II listed building. It is the tallest freestanding structure in the United Kingdom, and 25th tallest tower in the world. It was the seventh tallest freestanding structure and was fourth tallest tower in the European Union before Brexit. When built it was the sixth tallest freestanding structure in the world after the Ostankino Tower, the Empire State Building, 875 North Michigan Avenue (known as The John Hancock Center), the Berliner Fernsehturm and Tokyo Tower. The tower's current official name, The Arqiva Tower, is shown on a sign beside the offices at the base of the tower, but it is commonly known just as "Emley Moor Mast". In 2021, the antenna was removed due to technical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ostankino Tower
Ostankino Tower (russian: links=no, Останкинская телебашня, Ostankinskaya telebashnya) is a television and radio tower in Moscow, Russia, owned by the Moscow branch of unitary enterprise Russian TV and Radio Broadcasting Network. Standing , it was designed by Nikolai Nikitin, Pyotr Gorchakov and Yuri Kondratyuk. , it is the tallest free-standing structure in Europe and 12th tallest in the world. Between 1967 and 1974, it was the tallest in the world. The tower was the first free-standing structure to exceed in height.

British Insulated Callender's Cables
British Insulated Callender's Cables (BICC) was a 20th-century British cable manufacturer and construction company, now renamed after its former subsidiary Balfour Beatty. It was formed from the merger of two long established cable firms, Callender's Cable & Construction Company and British Insulated Cables. History Callender's Cable & Construction Company Callender's Cable & Construction Company was founded by William Ormiston Callender in 1870. It was originally an importer and refiner of bitumen for road construction but began manufacturing insulated cables at their Erith site on the Thames in the 1880s. It played a significant role in construction of the British National Grid (Great Britain), National Grid in the 1930s building the 400 kV Thames Crossing#132 kV Thames Crossing, 132 kV crossing of the Thames at Dagenham with overhead cables spanning 3060 feet (932m) between two 487 ft (148m) towers, and allowing 250 ft (76m) clearance for shipping.

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] |
Craigkelly Transmitting Station
The Craigkelly transmitting station is a broadcasting and telecommunications facility located at Craigkelly () north of the Firth of Forth above the town of Burntisland in Fife, Scotland. It has a 125-metre tall free-standing lattice tower rebuilt from a lattice tower originally located at the Emley Moor transmitting station. The station came into service in 1968 to improve coverage of BBC 2 to the Edinburgh area, which has a number of hills blocking good reception from Black Hill. In September 1971 it also started broadcasting BBC1 and Scottish Television on 625 lines in colour and though considered a 'main' station, it actually rebroadcast the signal from the Black Hill transmitting station, like a relay. Its tower now also carries antennas for many broadcasting and private radio organisations. This structure was previously used at Emley Moor. The transmitter was originally an A group but has become a K group (or wideband) with the advent of Channel 5 and Digital. Craigkelly is ...

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] |
Guyed Mast
A guyed mast or guyed tower is a tall thin vertical structure that depends on guy lines (diagonal tensioned cables attached to the ground) for stability. The mast itself has the compressive strength to support its own weight, but does not have the shear strength to stand unsupported. It requires guy lines to stay upright and to resist lateral forces such as wind loads. Guy lines are usually spaced at equal angles about the structure's base. Guyed masts are used for telecommunications, sailing, and meteorology. The tallest guyed mast in the world is currently the KVLY-TV mast near Blanchard, North Dakota, USA. Two subtypes exist. A ''partially guyed tower'' is a structure consisting of a guyed mast on top of a freestanding tower. The guys may be anchored to the top of the freestanding structure, or to the ground. A famous tower of this type is the Gerbrandy Tower. An ''additionally guyed tower'' is a freestanding tower which either has guys attached temporarily to add stab ...

ABC Weekend TV
ABC Weekend TV was the popular name of the British broadcaster ABC Television Limited, which provided the weekend service in the Midlands and Northern England regions of the Independent Television (ITV) network from 1956 to 1968. It was one of the " Big Four" companies that between them produced the majority of ITV networked programmes during this period. Originally created as Associated British Cinemas (Television) Ltd, ABC was one of a number of commercial television companies established during the 1950s by cinema chain companies, in an attempt to safeguard their business by becoming involved with television, which was taking away their cinema audiences. In this case, the parent company was the Associated British Picture Corporation (ABPC) — owner of ABC Cinemas — which initially did not wish to become involved with the new broadcasting system, but was persuaded to do so by the Independent Television Authority (ITA) and the manager of its Pathé News subsidiary Howard ...

ITV Granada
ITV Granada, formerly known as Granada Television, is the ITV franchisee for the North West of England and Isle of Man. From 1956 to 1968 it broadcast to both the north west and Yorkshire but only on weekdays as ABC Weekend Television was its weekend counterpart. Granada's parent company Granada plc later bought several other regional ITV stations and, in 2004, merged with Carlton Communications to form ITV plc. Granada Television was particularly noted by critics for the distinctive northern and "social realism" character of many of its network programmes, as well as the high quality of its drama and documentaries. In its prime as an independent franchisee, prior to its parent company merging with Carlton Communications to form ITV plc, it was the largest Independent Television producer in the UK, accounting for 25% of the total broadcasting output of the ITV network. Granada Television was founded by Sidney Bernstein at Granada Studios on Quay Street in Manchester and is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ITV (TV Network)
ITV is a British free-to-air public broadcast television network. It was launched in 1955 as Independent Television to provide competition to BBC Television (established in 1936). ITV is the oldest commercial network in the UK. Since the passing of the Broadcasting Act 1990, it has been legally known as Channel 3 to distinguish it from the other analogue channels at the time, BBC1, BBC2 and Channel 4. ITV was for four decades a network of separate companies which provided regional television services and also shared programmes between each other to be shown on the entire network. Each franchise was originally owned by a different company. After several mergers, the fifteen regional franchises are now held by two companies: ITV plc, which runs the ITV1 channel, and STV Group, which runs the STV channel. The ITV network is a separate entity from ITV plc, the company that resulted from the merger of Granada plc and Carlton Communications in 2004. ITV plc holds the Channel 3 ...

Lattice Tower
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 (a self-radiating tower or as a support for aerials) 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. Before 1940, they were used as radio transmission towers especially for short and medium wave. Occasionally lattice towers consisting of wood were utilized. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tokyo Tower
is a communications and observation tower in the Shiba-koen district of Minato, Tokyo, Japan, built in 1958. At , it is the second- tallest structure in Japan. The structure is an Eiffel Tower-inspired lattice tower that is painted white and international orange to comply with air safety regulations. The tower's main sources of income are tourism and antenna leasing. Over 150 million people have visited the tower. FootTown, a four-story building directly under the tower, houses museums, restaurants, and shops. Departing from there, guests can visit two observation decks. The two-story Main Deck (formerly known as the Main Observatory) is at , while the smaller Top Deck (formerly known as the "Special Observatory") reaches a height of . The names were changed following renovation of the top deck in 2018. The tower is repainted every five years, taking a year to complete the process. In 1961, transmission antennae were added to the tower. They are used for radio and televi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
