5. Place the Az/El cap over the screw holes in the back of the
antenna reflector (see Figure 17).
Make sure the Az/El cap mount screw holes are properly
aligned with the holes in the antenna reflector. The arrow on
the Az/El labeled TOP should point to the top of the antenna
reflector. Make sure the reflector is oriented so the section
with a hole in its rim is on the bottom.
6. Use a 7/16-in. socket or open-end wrench to install the four
5/16-in. self-tapping screws and flat washers in the holes.
Turn each screw clockwise until contact is made with the
mount surface. Then use a torque wrench with 1/2-in. socket
to tighten them to 10 ft-lbf. Do not overtighten.
