To connect the feed arm to the antenna reflector:

1.Insert the 5/16-18 wedge nut, thinner end first, into the slot provided on the back of the reflector, as shown in Figure 25. The wedge nut is keyed so that it will fit properly only one way into its slot in the reflector.

Make sure the hole in the wedge nut is aligned with the hole in the reflector so you can insert the bolt. See Figure 25.

2.Install the feed arm into the feed support socket on the underside of the antenna reflector.

If you have the reflector turned upside down to insert the feed arm, the orientation is the opposite of that shown in Figure 25.

3.Use a 1/2-in. wrench to secure the feed arm with a 5/16-in. flat washer, 5/16-in. lock washer, and 5/16-18 hex bolt. Use a torque wrench to tighten the hex bolt from 8 ft-lbf to 10 ft-lbf.
