   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.

   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.

   a Multiswitch with 16 outputs, the four cables from the Quattro-LNB enter on the left. A multiswitch is a device used with a dual or quattro LNB to distribute satellite TV signals to multiple (usually more than four) receivers from a single dish and LNB.

6. Feed horn - Wikipedia

   en.wikipedia.org/wiki/Feed_horn

   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).

7. Duo LNB - Wikipedia

   en.wikipedia.org/wiki/Duo_LNB

   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 ...
