2. Low-noise block downconverter - Wikipedia

   en.wikipedia.org/wiki/Low-noise_block_downconverter

   Today "dual LNB" (and "dual feed") describes antennas for reception from two satellite positions, using either two separate LNBs or a single Monoblock LNB with two feedhorns. In the UK, the term "twin-output LNB", or simply "twin LNB", is usually used for an LNB with a single feedhorn but two independent outputs. [3]

3. Monoblock LNB - Wikipedia

   en.wikipedia.org/wiki/Monoblock_LNB

   Two monoblock LNB can be connected to one receiving dish using Multi-satellite techniques. However, the expected results of such connections may vary or be sub-optimal. The results may yield low-level signals from some or all of the satellites or it may work well in certain geographically favorable locations.

4. Satellite dish - Wikipedia

   en.wikipedia.org/wiki/Satellite_dish

   In the LNB they become down converted to 950–2150 MHz, which is the frequency range allocated for the satellite service on the coaxial cable between LNBF and receiver. Lower frequencies are allocated to cable and terrestrial TV, FM radio, etc. Only one of these frequency bands fits on the coaxial cable, so each of these bands needs a separate ...

5. 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 ...

6. 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 ...

7. Duo LNB - Wikipedia

   en.wikipedia.org/wiki/Duo_LNB

   A twin-output Duo LNB fitted to a 60 cm dish with only one output connected. (Note that this LNB is mounted using the 19.2°E feedhorn, not in accordance with SES' installation guidelines) 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 ...

8. Orthomode transducer - Wikipedia

   en.wikipedia.org/wiki/Orthomode_transducer

   The transmission signal of the up-link, of relatively high power (1, 2, or 5 watts for common VSAT equipment) originating from BUC and the very low power received signal power (in the order of μV) coming from the antenna to the LNB receiver unit, in this case are at an angle of 90° relative to each other, are both coupled together at the feed ...

9. Transponder (satellite communications) - Wikipedia

   en.wikipedia.org/wiki/Transponder_(satellite...

   A communications satellite's transponder is the series of interconnected units that form a communications channel between the receiving and the transmitting antennas. [1] It is mainly used in satellite communication to transfer the received signals. A transponder is typically composed of: an input band-limiting device (an input band-pass filter),
