Installing the reflector
bracket and tilt plate
Begin the antenna assembly by attaching the antenna reflector
bracket and tilt plate to the Az/El mount:
1. Hold the reflector bracket in position over the Az/El mount so
that the tilt scale faces the mount, as shown in Figure 10.
2. While holding the reflector bracket in position, lay the tilt
plate over the opening in the reflector bracket so that the
holes in the tilt plate line up with the corresponding holes on
the Az/El mount. Because the hole pattern in the tilt plate is
not symmetrical, be sure that the tilt plate notch is at the top
so that you can line up the holes correctly.
3. Insert four carriage bolts (5/16-inch
×
¾-inch with ½-inch
hex head) into the holes in the tilt plate and through the holes
in the Az/El mount. You are going to bolt the tilt plate to the
Az/El mount, with the reflector bracket between them.
4. Place a ½-inch hex flange nut on each of the four bolts from
the opposite side and tighten the nuts lightly, only until snug.
Once connected, the reflector bracket should rotate freely
between the Az/El mount and the tilt plate.

Note: Tighten all bolts to a torque value of 8 ft-lb.
