Felsenegg-Girstel TV-tower
The Felsenegg Tower is a broadcasting tower located nearby Felseneggbahn mountain station on the Felsenegg vantage point in the canton of Zürich in Switzerland. The tower is owned by Swisscom Broadcast AG and generally not accessible by the public. History The Felsenegg Tower was built between 1959 and 1963 by architect Edwin Schoch from Zurich. Originally, it was designed for telephone transmission and broadcasting of radio and television programs. It was officially called Albis (abbreviated ALBS) by PTT (Swiss Telecom PTT, now Swisscom)Archiv PTT The tower was the number one national and international (Eurovision) technical control centre for TV transmissions and later, it was the connection point of many private TV stations in Switzerland allowing to connect to the national and international TV net. The REAL system switches antennas on other 27 Swisscom-towers. Today, Felsenegg is becoming less important, as the optical fiber technology will replace microwave radio techn ...

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] |
FM Broadcasting
FM broadcasting is a method of radio broadcasting using frequency modulation (FM). Invented in 1933 by American engineer Edwin Armstrong, wide-band FM is used worldwide to provide high fidelity sound over broadcast radio. FM broadcasting is capable of higher fidelity—that is, more accurate reproduction of the original program sound—than other broadcasting technologies, such as AM broadcasting. It is also less susceptible to common forms of interference, reducing static and popping sounds often heard on AM. Therefore, FM is used for most broadcasts of music or general audio (in the audio spectrum). FM radio stations use the very high frequency range of radio frequencies. Broadcast bands Throughout the world, the FM broadcast band falls within the VHF part of the radio spectrum. Usually 87.5 to 108.0 MHz is used, or some portion thereof, with few exceptions: * In the former Soviet republics, and some former Eastern Bloc countries, the older 65.8–74 MHz band ...

Chasseral
The Chasseral is a mountain of the Jura Mountains, overlooking Lake Biel in the Swiss canton of Bern. With an elevation of 1,606 metres above sea level, the Chasseral is the highest summit in the canton of Bern outside the Alps. It is also both the northernmost and easternmost mountain reaching over 1,500 metres in the Jura Mountains. West of the summit is located the Chasseral Ouest (1,552 m), where runs the border with the canton of Neuchâtel. The Chasseral Pass is located further on the west. The Chasseral is the fourth most topographically isolated mountain of Switzerland, although it is the first when considering only easily accessible summits. This results in a very extensive view over the other mountains of the Jura, the Swiss Plateau, the Alps, the Vosges and the Black Forest. The summit can be reached from the Chasseral hotel, where there is a bus stop. Climate See also * List of mountains of Switzerland * List of mountains of Switzerland accessible by public ...

Parabolic Antenna
A parabolic antenna is an antenna that uses a parabolic reflector, a curved surface with the cross-sectional shape of a parabola, to direct the radio waves. The most common form is shaped like a dish and is popularly called a dish antenna or parabolic dish. The main advantage of a parabolic antenna is that it has high directivity. It functions similarly to a searchlight or flashlight reflector to direct radio waves in a narrow beam, or receive radio waves from one particular direction only. Parabolic antennas have some of the highest gains, meaning that they can produce the narrowest beamwidths, of any antenna type. In order to achieve narrow beamwidths, the parabolic reflector must be much larger than the wavelength of the radio waves used, so parabolic antennas are used in the high frequency part of the radio spectrum, at UHF and microwave ( SHF) frequencies, at which the wavelengths are small enough that conveniently-sized reflectors can be used. Parabolic antennas are used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skyguide
Skyguide (Swiss Air Navigation Services Ltd.) is an air navigation service provider which manages and monitors Swiss airspace.

Radio Zürisee
Radio Zürisee (or radio zürisee according to the radio's logo; literally ''Radio Zürichsee''), is a privately-owned Switzerland, Swiss radio station based in Rapperswil on the shore of the Lake Zurich in the canton of St. Gallen. History Radio Zürisee was launched on 1 November 1983 in occasion of the licensing of private radio stations in Switzerland, as one of the first alternatives to the Swiss government-owned radio stations. In 2008, the station was allowed to establish a correspondent at the ''Federal Palace of Switzerland, Bundeshaus'' by the Swiss government – the ''Bundeshaus Radio'' is airing for all 16 private radio stations from the sessions of the Swiss parliament assembly in the capital city. Radio Zürisee moved in 1994 from Stäfa to Rapperswil to a location opposite of the Rapperswil railway station, from where it is still airing. In 2011, the Bernese radio ''Capital FM'' was bought by the Zürichsee Medien AG from Tamedia. Theodor Gut junior, editor in chi ...

Optical Fiber
An optical fiber, or optical fibre in Commonwealth English, is a flexible, transparent fiber made by drawing glass ( silica) or plastic to a diameter slightly thicker than that of a human hair. Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than electrical cables. Fibers are used instead of metal wires because signals travel along them with less loss; in addition, fibers are immune to electromagnetic interference, a problem from which metal wires suffer. Fibers are also used for illumination and imaging, and are often wrapped in bundles so they may be used to carry light into, or images out of confined spaces, as in the case of a fiberscope. Specially designed fibers are also used for a variety of other applications, some of them being fiber optic sensors and fiber laser ...
