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.
