405-line Transmitters Of The United Kingdom
Before they were decommissioned between 1982 and 1985, there were many instances of 405-line transmitters in the United Kingdom, having first been used in 1936. Below is a list of all transmitters: The 405-line transmitter network of the United Kingdom Alexandra Palace in London hosted the first 405-line transmitter, active between 1936 and 1939, then again from 1946 through to 1956. From 1949 onwards, the Band I VHF 405-line BBC transmitter network grew quickly. In 1955, with the advent of ITV a parallel effort to provide a Band III network was also underway. The pre-1955 BBC stations used the five channels of Band I, but with the introduction of Band III, some BBC stations started appearing there too (most of them on channels 12 or 13). All ITV transmitters were in Band III (mostly on channels 8, 9, or 10). There were eventually 41 high-power "main stations" owned by either the BBC or the IBA (see below). Most were built during the 1950s. The BBC's last main station to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
405-line Television System
The 405-line monochrome analogue television broadcasting system was the first fully electronic television system to be used in regular broadcasting. The number of television lines influences the image resolution, or quality of the picture. It was introduced with the BBC Television Service in 1936, suspended for the duration of World War II, and remained in operation in the UK until 1985. It was also used between 1961 and 1982 in Ireland, as well as from 1957 to 1973 for the Rediffusion Television cable service in Hong Kong. Sometimes called the Marconi-EMI system, it was developed in 1934 by the EMI Research Team led by Isaac Shoenberg. The figure of 405 lines had been chosen following discussions over Sunday lunch at the home of Alan Blumlein. The system used interlacing; EMI had been experimenting with a 243-line all-electronic interlaced system since 1933. In the 405 system the scanning lines were broadcast in two complementary fields, 50 times per second, creating 25 frame ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United Kingdom
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland.

Alexandra Palace Transmitting Station
The Alexandra Palace television station in North London () is one of the oldest television transmission sites in the world. What was at the time called "high definition" (405-line) TV broadcasts on VHF were beamed from this mast from 1936 until the outbreak of World War II. It then lay dormant until it was used very successfully to foil the German Y-Gerät radio navigation system during the last stages of the Battle of Britain. After the war, it was reused for television until 1956, when it was superseded by the opening of the BBC's new main transmitting station for the London area at Crystal Palace. In 1982 Alexandra Palace became an active transmitting station again, with the opening of a relay transmitter to provide UHF television service to parts of North London poorly covered from Crystal Palace. The transmitter is owned and maintained by Arqiva. Channels listed by frequency Analogue radio (FM) Digital radio (DAB) Digital television Digital television replaced the ...

Band I
Band I is a range of radio frequencies within the very high frequency (VHF) part of the electromagnetic spectrum. The first time there was defined "for simplicity" in Annex 1 of "Final acts of the European Broadcasting Conference in the VHF and UHF bands - Stockholm, 1961". Band I ranges from 47 to 68 MHz for the European Broadcasting Area, and from 54 to 88 MHz for the Americas and it is primarily used for television broadcasting in compliance with ITU Radio Regulations (article 1.38). With the transition to digital TV, most Band I transmitters have already been switched off. Television broadcasting usage Channel spacings vary from country to country, with spacings of 6, 7 and 8 MHz being common. In the UK, Band I was originally used by the BBC for monochrome 405-line television; likewise, the French former 455-line (1937-1939) then 441-line (1943-1956) transmitter on the Eiffel Tower in Paris, and some stations of the French monochrome 819-line system used Band I.

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 ...

Band III
Band III is the name of the range of radio frequencies within the very high frequency (VHF) part of the electromagnetic spectrum from 174 to 240 megahertz (MHz). It is primarily used for radio and television broadcasting. It is also called high-band VHF, in contrast to Bands I and II. Broadcast Television North America The band is subdivided into seven channels for television broadcasting, each occupying 6 MHz. Europe European Band III allocations vary from country to country, with channel widths of 7 or 8 MHz.

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] |

Llanelli Transmitting Station
The Llanelli transmitting station is a broadcasting and telecommunications facility located on high ground north of the town of Llanelli, South Wales. It was originally built by the BBC, entering service in mid 1970 transmitting the now-defunct 405-line VHF television system. As such, it was one of the last 405 transmitters ever built. UHF colour television was added to the mast in early 1975. Currently, the transmitter provides DVB-T digital television to the area, along with Scarlet FM radio and a single multiplex of DAB digital radio.
