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

This guidance is given for the replacement of an LNB on a Mk.4 elliptical dish and assumes that the dish is correctly aligned. If you have a different type of dish, it should be supplied with a 40mm dia. LNB bracket which is compatible with GeoSync LNB’s.

1) If you are trying to receive Sky™ or Freesat™ refer to the map opposite and align the bracket on the LNB at the appropriate angle, then tighten it securely.

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 and pull down the weather shield.
