This large device combines a quad LNB with a 'monoblock' able to simultaneously receive two satellites spaced apart by 4.3°, courtesy of a pair of accurately spaced feedhorns. It was designed for hassle-free reception of the Astra clusters at 19.2°E and 23.5°E, but similarly spaced satellites are fair game too. Thanks to all those outputs, four receivers (or two dual-tuner PVRs) in different rooms can independently select different channels of different polarity on either satellite.
