GK1LB Single LNB with MK4 Dish Bracket

Choosing the right LNB for Sky-Q or Freesat 4K


The GK1LB Universal SINGLE LNB can be used to receive signals from one of many satellites broadcasting signals down to us in the Ku frequency band. With a single outlet it offers the best value solution if all you have is a single satellite receiver.

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) Slide the weather-boot onto the cable and then connect it to the outlet. Having checked that the signal is OK pull the weather-boot up into position to protect the connection.
