Antenna Pointing - LNB Configuration

Polarizing the Circular LNB

The polarization of your LNB will vary depending on which satellite your satellite adapter card is commissioned to use.

  1. There is a special mark on the surface of the circular LNB, which will help you align the LNB and feedhorn.  The LNB and special mark are shown below.

  2. To align the feedhorn with the LNB for the G3R satellite, align the mark on the LNB with the center of the top of feedhorn as shown below.

    Note: Make sure that the word "TOP" on the feedhorn faces up


  3. To align the feedhorn with the LNB for the GE1 satellite, first align the mark on the LNB with the edge of the feedhorn that has the label "TOP".  Then by looking straight on at the feedhorn, twist the LNB counter clockwise until the mark is aligned with the next hole.  The pictures below show the correct way to align the feedhorn with the LNB.
