A low-noise block downconverter (LNB) is the receiving device mounted on satellite dishes used for satellite TV reception, which collects the radio waves from the dish and converts them to a signal which is sent through a cable to the receiver inside the building. Also called a low-noise block, [1][2] low-noise converter (LNC), or even low ...
DiSEqC (/ ˈdaɪsɛk, daɪˈsɛksi /; [citation needed] short for Digital Satellite Equipment Control) is a special communication protocol for use between a satellite receiver and a device such as a multi-dish switch or a small [1] dish antenna rotor. DiSEqC was developed by European satellite provider Eutelsat, which now acts as the standards ...
OTC Satellite Earth Station Carnarvon. The 12.8m-wide Casshorn antenna, commissioned in October 1966, has interacting parabolic and hyperbolic reflectors in a characteristic "sugar scoop" form. It claims to be the only remaining example in the world. The larger 29.8m parabolic dish antenna was commissioned in late 1969.
v. t. e. A satellite dish is a dish-shaped type of parabolic antenna designed to receive or transmit information by radio waves to or from a communication satellite. The term most commonly means a dish which receives direct-broadcast satellite television from a direct broadcast satellite in geostationary orbit.
A beam waveguide antenna is a type of complicated Cassegrain antenna with a long radio wave path to allow the feed electronics to be located at ground level. It is used in very large steerable radio telescopes and satellite ground antennas, where the feed electronics are too complicated and bulky, or requires too much maintenance and alterations, to locate on the dish; for example those using ...
A transmit and receive integrated assembly ( TRIA) is used on a two-way satellite dish to process signals to and from a ground-based system and an earth-orbiting satellite. The TRIA is the part of the antenna which contains both the feed horn and the circuits which convert high-frequency satellite signals such as X-band, Ku-band and Ka-band to ...
Broadband Global Area Network. The Broadband Global Area Network (BGAN) is a global satellite network with telephony owned by Inmarsat using portable terminals. [1] The terminals are normally used to connect a laptop computer to broadband Internet in remote locations, although as long as line-of-sight to the satellite exists, the terminal can ...
Satellite TV providers like DirecTV and EchoStar’s Dish were once some of the biggest distributors of the TV bundle. The competition ramped up when cable TV companies began offering broadband.
