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.
A cost-effective solution overcoming this obstacle may lead innovative designs of large matricesd of multiple LNBs tightly packed into a single monoblock LNB receiver. Another limiting factor is low awareness by the general population and satellite reception users of Multi Feed Multi satellite , and the fact that it is so easily possible.
Special LNBs have been developed for use in single-cable distribution systems. All four sub-bands of the Ku band (low frequency/horizontal polarity, high frequency/horizontal polarity, low frequency/vertical polarity, high frequency/vertical polarity) are received by a conventional front end, amplified and downconverted to the L-band, to be fed to a number of SatCR (Satellite Channel Router ...
The NS3000 Satellite Modem modulates and demodulates data and video signals transmitted via satellite. The "IP modem" (satellite modem) developed and made by Newtec of Belgium for SES' 2Mbit/s ASTRA2Connect European two-way satellite Internet system. Satellite modems are often used for home internet access.
A Duo LNB is a double low-noise block downconverter (LNB) developed by SES for the simultaneous reception of satellite television signals from both the Astra 23.5°E and Astra 19.2°E satellite positions. It is a monoblock LNB, which comprises two feedhorns with a single body of electronics containing the LNB stages along with switching ...
A virtual LNB with four electrical outputs for four tuners. The complete spectrum of Ku-band satellite reception stretches from 10.70 GHz-12.75 GHz across two signal polarisations, or a bandwidth of about 4000 MHz. This cannot be carried on a single coaxial cable and so in a conventional satellite reception system, just one of four sub-bands ...
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).
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.
