Unicable II

Unicable II programmable 40mm LNB with 24UB


Item: 5228


This Unicable2 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 Unicable2 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 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. The Unicable2 LNB 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.

Frequently Asked Questions

What is a feedhorn?

The feedhorn is the part of a satellite dish system which gathers the reflected signal from the dish and focuses it towards the LNB.

What is an LNB?

An LNB - Low Noise Block (also called an LNC- Low Noise Converter), is used for communications (broadcast) satellite reception. The LNB is usually affixed either in or on the satellite dish.

What is an LNBF?

An LNBF is an LNB with an integrated feedhorn

What is a Monoblock LNB?

This design consists of two independent LNBs in a single case. The two LNBs can be automatically addressed with any DiSEqC 1.0 or higher receiver. In some cases they can also be addressed with ToneBurst / MiniDiSEqC. However, they are only available for satellites with a fixed 3 degree, 4.3 degree, 6 degree …spacing. In Europe, for example, there are monoblock single, twin and quad LNBs for the Ku band, which have a pre-defined spacing of 6 degrees (for Astra 1 / Hotbird , for example).

Why can I receive only one satellite with my Monoblock?

Monoblock LNBs are designed for a specific dish size, 80cm for example. If your dish is too small (70cm for example) or too wide (90cm for example) it is not possible to receive both satellites together. Please choose the dish size for which the monoblock LNB has been designed.
