The Pedestal Mount is an elevation-over-azimuth mount optimized for geostationary
satellite applications. The mount enables continuous elevation adjustment from 0 to 90
degree. The azimuth axis has over 180 degrees of travel with 120 degrees (+/-60 deg.)
of continuous travel at each jack position. The jack can be positioned every 45 deg.
around the pedestal tube. Follow the subsequent procedures for proper installation of
pedestal ground mount assembly.
All ground mount hardware is type A325. Lubricate all A325 bolt threads with supplied
stick wax. Note: Do not tighten hardware until ground mount installation is complete
unless otherwise instructed.
Use a crane to carefully lift the pedestal assembly (303613) and place it over the corre-
sponding foundation bolts as shown in Figure 3. Note: Ensure pedestal assembly is ori-
ented on the foundation bolts as shown. Pedestal weight = approx. 3800 lbs. (1724 kg.)

Use 1-1/4 in. (32mm) hardware.
