Line of Sight (LOS) Adjustment
The following section describes the processes to adjust the antenna to the correct Line of Sight (LOS). It
includes both coarse and fine adjustment of the Azimuth and Elevation settings, along with the skew
adjustment process if required.
Skew Adjustment
Slightly loosen the five 5/16” x 3/4" UNC Carriage Bolts fastening the Elevation
Bracket to the Skew Plate through the Antenna Back Bracket. It should not take pressure to move the
dish; the dish should move freely. Manually rotate the dish to the required skew using markings on the
back of the Antenna Back Bracket as a guide. Once aligned correctly, use a meter to verify the Skew.
Then tighten the five 5/16” x 3/4" Carriage Bolts to 20Nm (177 in.lbf) using a ½” socket and Torque
Wrench.
