Installation Procedures
The ground mount assembly enables 180° positioning for selected azimuth viewing.
Azimuth range coverage is ±90° divided into three 120° continuous ranges with 30°
overlap. Elevation adjustment is continuous from 0 to 90°.
Position and mount 204737 azimuth tiller arm weldment to ground mount assembly as
shown using 0.75 x 1.75 in. A-325 bolts and nuts. Tighten hardware per A-325 tension-
ing procedure. NOTE: Mounting position of azimuth tiller arm weldment is dependent
upon predetermined azimuth range requirements as shown.
Apply supplied stick lubricant to set screw threads. Loosely install 0.50 x 1.0 in. set
screws in azimuth and 0.50 x 1.50 in. set screws in elevation strut supports.
Position and mount 204754 elevation support angle assembly to ground mount as
shown using 0.50 x 1.75 in. A-325 bolts, flat washers and nuts. Tighten hardware per A-
325 tensioning procedure.
Loosely install supplied 0.75 x 2.00 in. A-325 bolts, flat washers and nuts in elevation
support angle assembly. This hardware along with the upper elevation strut hardware
will be attached to the antenna and tightened to the A-325 tensioning procedure at the
time of antenna installation.
