This Unicable II™ LNB enables installations with up to 24 satellite receivers connected over a single coax cable and using the EN50494/EN50607 protocols providing access to unlimited number of transponders (also known as ‘Dynamic’ mode). Alternatively, it can be configured to deliver a fixed mapping of transponder frequencies to IF frequencies (also known as ‘Static’ mode), allowing an unlimited number of receivers to be connected and providing them access to up to 24 transponders (or more, depending on the bandwidth of the desired transponders) based on digital channel stacking technology.
Digital channel stacking technology uses fast wideband analog to digital converters and applies digital signal processing to select desired transponder channels, up convert them and stack them as IF signals over the Unicable output ports. The Unicable II™ LNB offers a full flexibility of channel selection, supports many more set-top-boxes over existing cabling thus significantly reducing cost and simplifying installations at subscribers’ homes. The Static mode, allowing an unlimited number of receivers to be connected to the LNB, makes multi-room distribution and MDU installations substantially cheaper and simpler than ever before. The operating mode - dynamic or static - output power level, channel bandwidth, UB numbers, center frequencies and dish alignment mode are all programmable and can be configured and updated in the field using a dedicated programmer device - the SatPal™ Controller*.
The LNB can be powered over a connected STB or by an AC/DC adapter over a power inserter in case the STB is unable to provide the necessary power. Unicable II™ is backward compatible, fully compliant with both EN50494 and EN50607 standards and integrates seamlessly into EN50494-only or mixed EN50494/EN50607 installations of compatible STBs, Next Generation PVRs and HGWs.

The feedhorn is a part of the LNB and works like a directional horn. Its function is to capture the signals reflected from the dish and to shield the LNB from receiving extraneous radiation from other sources. These collected signals are then passed form the horn to the electronics within the LNB.
HsQuare is a unique waveguide technology which may be coupled with a slightly larger feed horn design to deliver better RF performances compared with common circular microwave waveguides.
