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.
Automatic Tracking Satellite Dishes are satellite dishes used while a vehicle, boat or ship is in motion. Automatic tracking satellite dishes utilize gyroscopes, GPS position sensors, and uses unique satellite identification data and an integrated DVB decoder to aid in identification of the satellite that it is pointing at. The dishes consist ...
A polar mount is a movable mount for satellite dishes that allows the dish to be pointed at many geostationary satellites by slewing around one axis. [1] It works by having its slewing axis parallel, or almost parallel, to the Earth's polar axis so that the attached dish can follow, approximately, the geostationary orbit, which lies in the plane of the Earth's equator.
Feed horn with concentric rings (left) and LNB (right) on a Hughes DirecWay home satellite dish. An LNBF (LNB with integrated feed horn) that has been cut into two.Visible is the scalar horn antenna (the funnel with concentric rings), which couples the microwave beam into a short waveguide (the tube connecting the feed horn to the LNB electronics part of the LNBF).
The 64-metre (210 ft) diameter dish with the 18-metre (59 ft) dish in the foreground (mounted on rails and used in interferometry) The primary observing instrument is the 64-metre (210 ft) movable dish telescope, second largest in the Southern Hemisphere, and one of the first large movable dishes in the world (DSS-43 at Tidbinbilla was extended from 64-metre (210 ft) to 70-metre (230 ft) in ...
Monoblock LNB. Low-noise block downconverters (LNBs) [1] are electronic devices coupled to satellite dishes for TV reception or general telecommunication that convert electromagnetic waves into digital signals that can be used to transform information into human or machine interpretable data, e.g., optical images, video, code, communications, etc.
DirecTV offers two streaming options — DirecTV Stream, a contract-free internet TV bundle, and DirecTV via internet, which requires a signed contract and is available only through the Gemini device.
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.
