Multrå Transmitter
Multrå transmitter is a facility for FM-/ TV-broadcasting near Sollefteå in Sweden. It uses a guyed mast, which was built in 1964. This mast had before 1988 a height of . On February 7, 1988 the pinnacle collapsed as result of excessive icing. The lower parts of the mast remain standing and were repaired afterwards. The height of the mast was reduced to . T The ruins of the pinnacle is today a monument close to the transmission site. See also * List of tallest structures in Sweden A list of the tallest structures in Sweden.

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] |
Sollefteå
Sollefteå () is a locality and the seat of Sollefteå Municipality in Västernorrland County, Sweden with 8,562 inhabitants in 2010. The earliest written account on Sollefteå is found in a script dating back to 1270. During this time the name of the village was given as De Solatum - a name that can be interpreted as a composition of ''Sol'' (sun) and ''at'' (property) i.e. literally The sunlit region. ''De Solatum'' also can be interpreted as desolation, which means loneliness or remoteness (see Remote and isolated community). With Sollefteå being located at the lowest rapids of the Ångermanälven thereby making it the last outpost to which it was possible to sail. The village developed into a municipality. The town changed from a commercial town into a town dominated by the military when the two regiments T 3 (Logistics) and I 21 (Infantry) were located there in 1898 and 1911 respectively. In 1902 Sollefteå obtained the status of market town or ''köping'' before finally b ... [...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 ...

Transmission (telecommunications)
In telecommunications, transmission is the process of sending or propagating an analog or digital signal via a medium that is wired, wireless, or fiber-optic. Transmission technologies typically refer to physical layer protocol duties such as modulation, demodulation, line coding, equalization, error control, bit synchronization and multiplexing, but it may also involve higher-layer protocol duties, for example, digitizing an analog signal, and data compression. Transmission of a digital message, or of a digitized analog signal, is known as data transmission. Examples of transmission are the sending of signals with limited duration, for example, a block or packet of data, a phone call, or an email. See also *Radio transmitter 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
