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. The signals are received via an outdoor parabolic antenna commonly referred to as a satellite dish and a low-noise block downconverter.. A satellite receiver then decodes the desired television program for viewing.
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. Mounted on brackets at the dish's focal point is a device called a feedhorn.
This feedhorn is essentially the front-end of a waveguide that gathers the signals at or near the focal point and 'conducts' them to a low-noise block downconverter how to free satellite tv LNB. A new form of omnidirectional satellite antenna, which does not use a directed parabolic dish and can be used on a mobile platform such as a vehicle was announced by the University of Waterloo in The theoretical yo directive gain of a dish increases as the frequency increases.
The actual gain depends on many factors what bodies of water surround south africa surface finish, accuracy of shape, feedhorn matching. A typical value for a consumer type 60 cm satellite dish at With lower frequencies, C-band for example, dish designers have a wider choice of materials.
The large size of dish required for lower frequencies led to the dishes being constructed from metal mesh on a metal framework. At higher frequencies, mesh type designs are rarer though some designs have used a solid dish with perforations. For instance, one BBC News downlink shows a "red signal" being received by the LNBF directly instead how to make logos on shirts being beamed to the dish, which because of its parabolic shape will collect the signal into a smaller area and deliver it to the LNBF.
Modern dishes intended for home television use are generally 43 cm 18 in to 80 cm 31 in in diameterand are fixed in one position, for Ku-band reception from one orbital position. Prior to the existence of direct broadcast satellite services, home users would generally have a motorised C-band dish of up to 3 m in diameter for reception of channels from frer satellites.
Overly small dishes can still cause problems, however, including rain fade and interference hoow adjacent satellites.
In Europethe frequencies used by DBS services are This range is divided into a "low band" with This results in two frequency bands, each with a bandwidth of about 1 GHz, each with two possible polarizations. Lower frequencies are allocated to cable and terrestrial TVFM radio, etc. Only satsllite of these frequency bands fits on the coaxial cable, so each of these bands needs a separate cable from the LNBF to a switching satellitee or the receiver needs to select one of the 4 possibilities at a time.
In a single receiver residential installation there is a single coaxial cable running from the receiver set-top box in the building to the LNB on the dish. The DC electric power for the LNB is provided through the same coaxial cable conductors that carry the signal to the receiver. In addition, control signals are also transmitted from the receiver to the LNB through the cable. In larger installations each band and polarization is given its own cable, so there are 4 cables satelite the LNB to a 'multiswitch' switching matrix, which allows the connection of multiple receivers to the multiswitch in a star topology using the same signalling method as in a single receiver installation.
A satellite finder or sat finder is a satellite field strength meter used to accurately point satellite dishes at communications satellites in geostationary orbit. A dish that is mounted on a pole and driven by a stepper motor or a servo can be controlled and ho to face any satellite position in the sky. Many receivers support all of these standards. Motor-driven dishes come in a variety of sizes, but a dish of at least centimetres 47 in is required to receive signals from distant satellites which are intended to serve other areas.
With DiSEqC and USALS, the satellite dish will automatically aim itself at one of sixteen satellites programmed in previously when pressing one of the channel buttons on the remote. Most receivers sold at present [ when? However, some designs much more effectively optimize simultaneous reception from multiple different satellite positions without re-positioning the dish.
The vertical axis operates as an off-axis concave parabolic concave hyperbolic [ clarification needed ] Cassegrain reflectorwhile the horizontal axis operates as a concave convex [ clarification needed ] Cassegrain. The spot from the main dish wanders across the secondary, which corrects astigmatism by its varying curvature.
The elliptic aperture of the primary is designed to fit the deformed illumination by the horns. Due to double fre, this makes more sense for a large dish. Most receivers sold presently [ when? DiSEqC 1. Motor-driven dishes assure better optimal focusing for the given dish size; LNB is always in central alignment with the broadcasting satellite, but DiSEqC switches are faster than DiSEqC motors as no physical movement is required.
A common type of dish is the very small aperture terminal VSAT. This provides two way satellite Internet communications for both individuals and private networks for organizations. At present, [ when? Indish manufacturers began moving towards new K a band satellites operating at higher frequencies, offering greater performance at lower cost. General Electric satellite dish for DirecTV satellite television.
Sky " minidish ". The back side of an old C-band satellite dish showing the pole, mount, motor, and structure of the dish. Any metal surface which concentrates a significant fraction of the reflected microwaves hpw a focus can be used as a dish antenna, at a lower gain.
This has led to trash can lids, woks, and other items how to make cord rosary bracelet used as "dishes". Parabolic antennas referred to as "dish" antennas had been in use long before satellite television.
Taylor Howard of San Andreas, Californiaadapted hiw ex-military dish in and became the first person to receive satellite television signals using it. The first satellite television dishes were built to receive signals on the C-band analog, and were very large. The sate,lite cover of the Neiman-Marcus Christmas catalog featured the first home satellite TV stations on sale. Satellite dishes made of wire mesh first came out in the early s, and were at first 10 feet 3.
As the front-end technology improved and the noise figure of the LNBs fell, the size shrank to 8 feet 2. In the early s, four large American cable companies founded PrimeStara direct broadcasting company using medium power satellites. This great decrease of dish size also allowed satellite dishes to be installed on vehicles. Television stations, however, still prefer to transmit their signals on the C-band analog with large dishes due to the fact that C-band signals are less prone to rain fade than K u band signals.
