Installing the antenna assembly onto the mast

To satellite

This section describes how to install the antenna assembly (including the Az/El cap) onto the mast.

To install the antenna assembly onto the mast:

1.Lightly grease the area at the end of the mast or metal pole that will be covered by the Az/El cap canister. This makes it easy to rotate the antenna to adjust the azimuth. Any grease will do; you can use automotive grease or household grease such as Vaseline.

2.Use a 1/2-in. open-end wrench to loosen the three clamp nuts and the elevation pivot bolt nut so the collar can slide over the mast or metal pole.

3.Lift the antenna assembly and slide the Az/El cap onto the mast or metal pole (see Figure 26).

The antenna should face toward the satellite.

4.Tighten the clamp nuts all the way, then loosen them just enough to move the antenna reflector from side to side and adjust the azimuth. The clamp bolts should be as snug as possible, but still allow the antenna reflector to be moved from side to side.
