4. Secure the assembly by placing a flat washer, lock washer,
and ½-inch nut on each carriage bolt, as shown in Figure 11
on page 19. Tighten each nut to 8 ft-lb using a torque wrench.
Once connected, the reflector bracket should rotate freely
between the Az/El mount and the tilt plate.
When the reflector bracket and tilt plate are correctly
positioned on the Az/El mount assembly, you should be able
to clearly see the tilt scale numbers on the reflector bracket
from the rear, as shown in Figure 12.
Installing the
feed support arms
and tailpiece
Installation of the feed support arm is a two-step process. First,
you must connect the two feed support arms to the reflector
bracket; then you will connect the tailpiece (sometimes referred
to as the “beaver tail”) to the ends of the feed support arms.
1. Insert the feed support arms into the two sockets at the
bottom of the reflector bracket, as shown in Figure 13.
Figure 12: Aligning the Az/El mount
Note: Tighten all 5/16-inch bolts to a maximum torque of
8 ft-lb.
Note: The two feed support arms are not identical. Be sure
to insert each arm into its appropriate socket as shown in the
figure, so that the holes in the feed support arms line up with
the corresponding holes in the reflector bracket.
