Installing one of our products should be as straight-forward as possible which is why we incorporate a number of design features to help. GeoSync LNB’s are a great example of a product range designed for the UK, based on a detailed understanding the most popular dish designs that are used and the alignment requirements of the satellite which provides both Sky™ and Freesat™ signals.

Are you replacing an LNB on a Mk4 elliptical satellite dish? Then installation is as easy as 1, 2, 3.

Assuming that your dish is correctly aligned:

1) To receive Sky™ or Freesat™ align the bracket on the LNB at the appropriate angle shown on the map included with your LNB and tighten securely.

As you move from the North East to the South West the amount of skew required to align with the satellite increases in the negative direction.

Markings on the neck of the LNB should be aligned with the “V” on the bracket collar.

2) Having removed the old LNB slot the bracket onto the satellite dish arm and secure it in place with the split pin.

3) Connect each of the coax cables to the outlets on your new LNB, check the signal and pull down the weather shield
