Installing the
antenna assembly
onto the mast pipe
Follow these steps to install the assembled antenna assembly onto
the mast pipe:
1. Before you install the Az/El mount assembly onto the mast

mast must be plumb before you install the antenna assembly.
Check the mast at two locations, 90° apart, as shown in
Figure 23.
2. Slide the Az/El mount assembly canister down onto the mast
pipe as shown in Figure 24.
