Installing the antenna
assembly onto the
mast pipe
Follow these steps to install the antenna assembly onto the mast:
1. Before you install the assembled antenna assembly onto the
mast pipe, use a bubble level to make sure the mast is plumb.
Check the mast at two perpendicular locations, as shown in
Figure 21.
2. Slide the canister of the Az/El and reflector bracket assembly
down onto the mast.
Figure 22 shows the Az/El and reflector bracket assembly on
the mast.
Note: The mast must be plumb. The antenna assembly
cannot be adjusted to correct for a mast that is not plumb.
