SUGGESTED MAST AND FOUNDATIONS
NOTE: Due to the wide variety of soil conditions, Prodelin Corporation does not warrant that
any particular design or size of foundation is appropriate for any locality or earth station
installation. It is the responsibility of the installer/user to determine if it meets the site/locality
requirements. If there is any doubt, have it checked by an architect or structural engineer.

IN-GROUND MAST MOUNT
Figure 1 shows a suggested In-Ground Mast. The pipe is a 15 ft. length of 10"
schedule 40. Due to the high cost of shipping, Prodelin recommends site
procurement. Note that the Az/El Positioner Interface is a Slip Flange, which is
included with the antenna.

PEDESTAL FOUNDATION
Figure 2 shows a suggested Pad Foundation and figure 3 shows a suggested
Pier Foundation. Both foundations utilize Prodelin's Pedestal Mount. To install
the Pedestal Mount foundation, follow the steps below.
1.
Install one [1] 1-8 hex nut and one [1] 1" flatwasher (items 2,3) onto the anchor
rod (item 5), then insert the anchor rod into one of the holes in the plywood
template (item 6) and install another 1-8 hex nut and 1" flatwasher. Repeat this
procedure for the remaining anchor rods. This will keep all the anchor rods in the
straight and proper orientation when the concrete is poured. Next, install two [2]
1-8 hex nuts and one [1] flatwasher (items 2,3) on the other end of each anchor
rod. See following pad layout and figures 2 & 3.
2.
Once the site location is determined, dig up the area where the foundation will be
installed. Be careful not to dig too deep because the soil in the bottom and sides
of the foundation should be undisturbed. Position the reinforcing bars as shown.
Position the anchor rods so that the flatwashers are positioned under the
reinforcing bars. Pour concrete and allow to dry for 24 hours.
3.
Once the concrete is dry, remove the plywood template and screw the lower hex
nuts as far down on the anchor rods as possible. Then install the mast pipe (item
1) on to the anchor rods. Adjust the lower hex nuts until the mast pipe is level in
the vertical position. Reinstall the flatwashers, lockwashers and hex nuts. With
the mast pipe tightened down, fill the space between the concrete slab and the
mast pipe base with grout.
