This is a list of the free-to-air channels that are currently available via satellite from SES Astra satellites (Astra 2E/2F/2G) at orbital position 28.2 °E, serving Ireland and the United Kingdom. Sky and Freesat use these satellites to deliver their channels.
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.
When using a satellite single cable distribution system for pay-TV subscriptions, end-users need to choose between multiple incompatible receivers compliant with either a single unicable LNB or a multi-Feed, multi-satellite reception by twin or quad Monoblock LNB, unless they intend to use two or four separate cables connected to alternative ...
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 .
North American frequency assignments differ from those used in Europe and other countries. Typically, the lower half of the Ku band contains communications satellites and free-to-air or ethnic-language programming, using linearly-polarised LNBs; the upper half of the Ku band contains circular-polarised direct broadcast satellite signals.
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 first certified SAT>IP equipment to be produced for commercial sale was the IDL400S Multibox server from Inverto. The Linux-based Multibox can tune to four satellite signals and stream selected TV/Radio programs to four users' tablets, smart phones, smart TVs, game consoles or connected video devices over a wired and/or wireless home network.
A Viewsat Xtreme FTA receiver. A free-to-air or FTA Receiver is a satellite television receiver designed to receive unencrypted broadcasts. Modern decoders are typically compliant with the MPEG-4/DVB-S2 standard and formerly the MPEG-2/DVB-S standard, while older FTA receivers relied on analog satellite transmissions which have declined rapidly in recent years.
