assembly Follow these steps to install the Az/El and reflector bracket
assembly onto the mast:
1. Before you install the Az/El and reflector bracket 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 14.
2. Slide the canister of the Az/El and reflector bracket assembly
down onto the mast.
Figure 15 shows the Az/El and reflector bracket assembly on
