Vigra Transmitter
Vigra transmitter was a transmitter facility for medium wave broadcasting near Vigra in Norway. The Vigra transmitter was inaugurated by the Norwegian Broadcasting Corporation (NRK) in . It was used until 1953 for transmission with a T-antenna. This antenna was replaced in 1952/53 by a guyed, steel-tube mast radiator insulated against the earth with a height of 243 metres. In 1999, the height of the mast was reduced for air traffic safety reasons to 232 metres. The Vigra transmitter frequency was 630 kHz with a power of 100 kilowatts, enabling it to be received at night in much of Europe, with the daytime signal taking in Iceland, the Faroes, Shetland and Orkney Islands, Scotland and up to Andøya Island in Norway. The service was shut down on , and the high antenna was demolished on September 8, 2011 with help from the Norwegian Armed Forces The Norwegian Armed Forces ( no, Forsvaret, , The Defence) is the military organization responsible for the defence of Norway.

Medium Wave
Medium wave (MW) is the part of the medium frequency (MF) radio band used mainly for AM radio broadcasting. The spectrum provides about 120 channels with more limited sound quality than FM stations on the FM broadcast band. During the daytime, reception is usually limited to more local stations, though this is dependent on the signal conditions and quality of radio receiver used. Improved signal propagation at night allows the reception of much longer distance signals (within a range of about 2,000 km or 1,200 miles). This can cause increased interference because on most channels multiple transmitters operate simultaneously worldwide. In addition, amplitude modulation (AM) is often more prone to interference by various electronic devices, especially power supplies and computers. Strong transmitters cover larger areas than on the FM broadcast band but require more energy and longer antennas. Digital modes are possible but have not reached momentum yet. MW was the main radio ban ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broadcasting
Broadcasting is the distribution (business), distribution of sound, audio or video content to a dispersed audience via any electronic medium (communication), mass communications medium, but typically one using the electromagnetic spectrum (radio waves), in a :wikt:one-to-many, one-to-many model. Broadcasting began with AM radio, which came into popular use around 1920 with the spread of vacuum tube radio transmitters and radio receiver, receivers. Before this, all forms of electronic communication (early radio, telephone, and telegraph) were wikt:one-to-one, one-to-one, with the message intended for a single recipient. The term ''broadcasting'' evolved from its use as the agricultural method of sowing seeds in a field by casting them broadly about. It was later adopted for describing the widespread distribution of information by printed materials or by telegraph. Examples applying it to "one-to-many" radio transmissions of an individual station to multiple listeners appeared as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vigra
Vigra is a former municipality in Møre og Romsdal county on the west coast of Norway. The municipality existed from 1890 until its dissolution in 1964 when it was merged into the present-day Giske Municipality. The former municipality was made up of the island of Vigra along with many smaller islets surrounding it. The administrative centre of the municipality was the village of Roald, and Vigra Church was the main church for the municipality. Also, ''Vigra'' a meteorology term which is precipitation from a cloud that never reaches the surface. History On 1 January 1890, the western islands in Haram Municipality were separated from Haram and established as ''Roald'' Municipality. The initial population was 794. In 1911, the name of the municipality was changed to ''Vigra''. During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1964, the whole municipality of Vigra was merged into the neighboring Giske Munici ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

T-antenna
A T-antenna, T-aerial, flat-top antenna, or (capacitively) top-loaded antenna is a monopole radio antenna with transverse capacitive loading wires attached to its top. T-antennas are typically used in the VLF, LF, MF, and shortwave bands, and are widely used as transmitting antennas for amateur radio stations, and long wave and medium wave AM broadcasting stations. They can also be used as receiving antennas for shortwave listening. The antenna consists of one or more horizontal wires suspended between two supporting radio masts or buildings and insulated from them at the ends. A vertical wire is connected to the center of the horizontal wires and hangs down close to the ground, connected to the transmitter or receiver. Combined, the two sections form a ‘T’ shape, hence the name. The transmitter power is applied, or the receiver is connected, between the bottom of the vertical wire and a ground connection. The T-antenna functions as a monopole antenna with capacitive t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Former Radio Masts And Towers
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ad ...

Transmitter Sites In Norway
In electronics and telecommunications, a radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. When excited by this alternating current, the antenna radiates radio waves. Transmitters are necessary component parts of all electronic devices that communicate by radio, such as radio and television broadcasting stations, cell phones, walkie-talkies, wireless computer networks, Bluetooth enabled devices, garage door openers, two-way radios in aircraft, ships, spacecraft, radar sets and navigational beacons. The term ''transmitter'' is usually limited to equipment that generates radio waves for communication purposes; or radiolocation, such as radar and navigational transmitters. Generators of radio waves for heating or industrial purposes, such as microwave ovens or diathermy equipment, are not usually called transmitters, even ...
