Step 4

Position and mount the azimuth tiller arm (P/N 203112) to the tiller-arm bracket on the left side (facing the satellite) of the ground mount assembly. This mounting position of the azimuth tiller arm is dependent upon pre-determined azimuth range requirements as shown in Figure 3-11.

NOTE: The ground mount assembly enables 180 degrees positioning for selected azimuth viewing. Azimuth range coverage is plus or minus 90 degrees, divided into three 120 degree continuous ranges with a 30 degrees overlap. Elevation adjustment is continuous from 0 degrees to 90 degrees.
