Arfon Transmitting Station
The Arfon transmitting station is a facility for FM, DAB digital radio and television transmission near the villages of Nebo and Nasareth in Gwynedd, northwestern Wales (). It includes a guyed mast with antennas attached at various heights. The mast is surmounted by a television transmitting antenna, which brings the total height of the structure to , making it the tallest structure in Wales. It is owned and operated by Arqiva. History The station was built by the ITA in the early 1960s to provide a 405-line ITV Band III ( VHF) TV service for north west Wales. Unlike the BBC, which served the area from Llanddona (on the island of Anglesey), Arfon gave better coverage to some areas. The tower was completed in 1962 and began broadcasting on 9 November of that year. In October 1975 the site became a medium power UHF analogue colour television relay of Llanddona, at the time carrying BBC One, BBC Two and ITV. S4C was added in 1982. 405-line TV was finally discontinued in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Nebo Relay Mast - Geograph
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a v ...

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. The standard channel allocations for European countries that use System B with 7 MHz channel spacing are as follows: The Irish (8 MHz) system is shown below. Oceania Australia has allocated 8 channels in Band III for digital television, each with 7 MHz bandwidth. Russia and other former members of OIRT Russian analog television is transmitted using System D with 8 MHz channel bandwidth. Radio The band came into use for radio broa ...

Llŷn Peninsula
The Llŷn Peninsula ( cy, Penrhyn Llŷn or , ) extends into the Irish Sea from North West Wales, south west of the Isle of Anglesey. It is part of the historic county of Caernarfonshire, and historic region and local authority area of Gwynedd. Much of the eastern part of the peninsula, around Criccieth, may be regarded as part of Eifionydd rather than Llŷn, although the boundary is somewhat vague. The area of Llŷn is about , and its population is at least 20,000. Historically, the peninsula was travelled by pilgrims en route to Bardsey Island (Welsh: ''Ynys Enlli''), and its relative isolation has helped to conserve the Welsh language and culture, for which the locality is now famous. This perceived remoteness from urban life has lent the area an unspoilt image which has made Llŷn a popular destination for both tourists and holiday home owners. Holiday homes remain contentious among locals, many of whom are priced out of the housing market by incomers. From the 1970s to the 199 ...

Light-emitting Diode
A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor. White light is obtained by using multiple semiconductors or a layer of light-emitting phosphor on the semiconductor device. Appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared (IR) light. Infrared LEDs are used in remote-control circuits, such as those used with a wide variety of consumer electronics. The first visible-light LEDs were of low intensity and limited to red. Early LEDs were often used as indicator lamps, replacing small incandescent bulbs, and in seven-segment displays. Later developments produced LEDs available in visible, ultraviolet (UV) ...

Aircraft Warning Lights
Aviation obstruction lighting is used to enhance the visibility of structures or fixed obstacles which may conflict with the safe navigation of aircraft. Obstruction lighting is commonly installed on towers, buildings, and even fences located in areas where aircraft may be operating at low altitudes. In certain areas, some List of aviation regulatory bodies, aviation regulators mandate the installation, operation, color, and/or NOTAM, status notification of obstruction lighting. For maximum visibility and collision-avoidance, these lighting systems commonly employ one or more high-intensity Strobe light, strobe or LED lamp, LED devices which can be seen by Aircraft pilot, pilots from many miles away from the obstruction. Lamp types The lights generally come in two forms: * Red lamps that are either constantly illuminated or turn on and off slowly in a cycle of a few seconds. * White xenon flash lamps. Both types were in use in the United Kingdom until recently. New r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

BBC Two
BBC Two is a British free-to-air public broadcast television network owned and operated by the BBC. It covers a wide range of subject matter, with a remit "to broadcast programmes of depth and substance" in contrast to the more mainstream and popular BBC One. Like the BBC's other domestic TV and radio channels, it is funded by the television licence, and is therefore free of commercial advertising. It is a comparatively well-funded public-service network, regularly attaining a much higher audience share than most public-service networks worldwide.
