The pedestal assembly is shipped pre-assembled and is comprised of the V-frame
weldment pinned to the pedestal weldment in two places.
Figure 2. Pedestal Assembly
Step 1. Determine the desired antenna orientation and place the pedestal on the foundation
anchor bolts with the V-frame pointing in the desired direction (foundation hardware is
shipped with the foundation kit). The antenna will typically face south in northern
latitude installations and north in southern latitude installations.
Note: One inch of grout may be used in tracking configurations.
Note: The pedestal assembly should be lifted into place as an assembly using
adequate lifting equipment such as a forklift or hoist.
Step 2. Locate the four 1” x 4” x 4” plate washers and place them on each of the four anchor
bolts. Use a bubble level positioned on the top and sides of the pedestal to ensure
that it is level, both horizontally and vertically.
Step 3. Install one washer and one nut (included in the foundation kit) on each of the four
anchor bolts. Torque the anchor bolt nuts to 740 ft. lbs. ± 10% dry or 560 ft. lbs. ±
10% lubricated.
