ODU Installation

Note Installers are responsible for supplying mounting bolts.

Ground Mast All steel mounting structures attached to the building and the

antenna mast must be connected to the building grounding

system. If no grounding system or ring is available, ground the

antenna mounting structures to the nearest structural beam. The

grounding conductor should be set at least a # 2 (AWG) solid

tinned copper wire. Use exothermic welds (Cad Welds) when

possible to connect to the mounting structure and the building

grounding system.

Antenna Mounting 1. Attach the ODU mounting bracket to a mast between 2- and 4-

inches in diameter (1 in Figure 6-1).

2. Remove the nuts and washers (2 in Figure 6-1) from one side of

each of the two mounting clamps (3) and slide the mounting

clamps off the bolts. Set them aside in a safe place.

3. Slip the mounting rack (4 in Figure 6-1) around the mast.

4. Reattach each of the two mounting clamps with the flat washer,

lock washer, and nut.

5. Tighten with a 1/2-inch socket wrench until secure.
