Global Stacker De-Stacker system

The Global Stacker De-Stacker solves the problem of upgrading your Sky/Sky Plus/Sky HD system cabling. It allows you to have 2 LNB feeds sent over a single co-ax cable. This means that you can upgrade from Sky to Sky HD or Sky Plus without running an extra co-ax cable from the dish through you house damaging your decor. It also means that you can upgrade from a single Sky Plus box to Sky Mulitroom with 2 Sky boxes runing over 2 runs of co-ax cable.

How far is the cable to run?

The Global Stacker De-Stacker is designed to work with cable runs of up to 30 metres of CT100 co-ax cable.

The Global Stacker De-Stacker Plus is designed to work with cable runs of up to 60 metres of CT100 co-ax cable.

How does it work?

The Global Stacker De-Stacker is used on the downlink to your Sky decoder. The Stacker converts the two LNB signals such that they can co-exist on the same piece of co-ax without interferring with each other, by moving one of the LNB to a higher frequency. The De-Stacker reverses this process.

No other TV amplifiers, splitters, connectors, etc can be introduced between the Stacker and De-Stacker, as this will disable the operation of the system.

The Stacker box is mounted directly behind the LNB and has two inputs (47-2,150 MHz and 950-2,150 MHz) and one output (47-3,550 MHz). You connect two of your LNB outputs to the Stacker unit. Connect the Stacker output via single cable (with no joints or wall plates interposed) to the De-Stacker input. All connectors are satellite screw fit 'F' type.

Two short coax cables link the two Destacker outputs to the two LNB inputs on the Sky HD (or Sky Plus) decoder. Whilst you must not use a wall outlet for the single co-ax cable run from the Stacker, you may use wall outlets after the DeStacker, before the Sky box.

It is critical that the single run of co-ax cable is of the highest quality (at least CT100 specification), and is one continuous length, without kinks or sharp bends.
