  2. Low-noise block downconverter - Wikipedia

    en.wikipedia.org/wiki/Low-noise_block_downconverter

    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.

  3. Monoblock LNB - Wikipedia

    en.wikipedia.org/wiki/Monoblock_LNB

    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.

  4. Single-cable distribution - Wikipedia

    en.wikipedia.org/wiki/Single-cable_distribution

    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 ...

  5. Satellite modem - Wikipedia

    en.wikipedia.org/wiki/Satellite_modem

    A satellite modem is not the only device needed to establish a communication channel. Other equipment that is essential for creating a satellite link include satellite antennas and frequency converters. Data to be transmitted are transferred to a modem from data terminal equipment (e.g. a computer).

  6. Block upconverter - Wikipedia

    en.wikipedia.org/wiki/Block_upconverter

    An example of a system utilizing both a BUC and an LNB is a VSAT system, used for bidirectional Internet access via satellite. The block upconverter is a block shaped device assembled with the LNB in association with an OMT, orthogonal mode transducer to the feed-horn that faces the reflector parabolic dish. This is opposed to other types of ...

  7. Duo LNB - Wikipedia

    en.wikipedia.org/wiki/Duo_LNB

    The Astra 23.5°E orbital position was established as a major source of direct-to-home (DTH) broadcasts for central and western Europe with the launch of Astra 3A at the end of 2007, [3] and some channels moved there from other satellite positions (in particular 19.2° east) so viewers, who were unable to erect two dishes to receive transmissions from both positions, had to choose between them.

  8. FTA receiver - Wikipedia

    en.wikipedia.org/wiki/FTA_receiver

    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.

  9. Fibre satellite distribution - Wikipedia

    en.wikipedia.org/wiki/Fibre_satellite_distribution

    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 ...
