The Minidish is the tradename used for the small-sized satellite dish used by Freesat and Sky. The term has entered the vocabulary in the UK and Ireland as a generic term for a satellite dish, particularly small ones. [citation needed] The Minidish is an oval, mesh satellite dish capable of reflecting signals broadcast in the upper X band and K ...
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 .
However, in many cases, it is also that which makes the program free (and sometimes open source [1]), avoid the need of an Internet connection, [2] [3] [4] and make it very lightweight (allowing use on small portable devices, including smartphones). Very basic programs like this may not be suitable for road navigation in cars, but serve their ...
A number of satellite dishes. Satellite television is a service that delivers television programming to viewers by relaying it from a communications satellite orbiting the Earth directly to the viewer's location. [1] The signals are received via an outdoor parabolic antenna commonly referred to as a satellite dish and a low-noise block ...
A 2.5 m parabolic dish antenna for bidirectional satellite Internet access. A very-small-aperture terminal (VSAT) [1] is a two-way satellite ground station with a dish antenna that is smaller than 3.8 meters. The majority of VSAT antennas range from 75 cm to 1.2 m. Bit rates, in most cases, range from 4 kbit/s to 16 Mbit/s.
In small dishes such as home satellite dishes, where the size of the feed structure is comparable with the size of the dish, this can seriously reduce the antenna gain. To prevent this problem these types of antennas often use an offset feed, where the feed antenna is located to one side, outside the beam area. The aperture efficiency for these ...
A direct broadcast satellite is a communications satellite that transmits to small DBS satellite dishes (usually 18 to 24 inches or 45 to 60 cm in diameter). Direct broadcast satellites generally operate in the upper portion of the microwave K u band.
DirecTV supplies BBCs with all 5-LNB K u /K a-band dish systems. The satellite signal from T10 is downconverted at the dish to the frequency range of 250-750 MHz, called "K a-lo". At the receiver when necessary, the BBC in response to a control signal from the receiver blocks any original "K a-hi" signals between 1650-2150 MHz. Then up-converts ...
