CONNECTING THE FEED ARM TO THE SATELLITE DISH
PARTS NEEDED
• Feed arm with feed assembly (LNB and waveguide) attached
• Satellite dish
• 5/16-18 wedge nut
• 5/16-18 hex bolt
• 5/16-inch flat washer
• 5/16-inch lock washer
TOOLS NEEDED
• 1/2-inch open-end wrench or socket wrench
• Torque wrench (with 1/2-inch socket capable of torquing to 10 ft-
lbs.)
Note: Be sure that the feed arm and feed assembly are positioned as
shown in Figure 35.
Note: If you are installing the satellite dish assembly on a metal pole
mount, it is probably easiest to attach the feed arm after you have
installed the satellite dish on the pole. See “Installing the satellite
dish/cap assembly onto the mast” on page 27.. However, if you are
using a ladder, it may be easier to attach the feed arm to the satellite
dish before installing it on the mast or metal pole.
1. Insert the 5/16-18 wedge nut thin end first into the slot pro-
vided on the back of the satellite dish. The wedge nut is
keyed so that it will fit properly in its slot in the dish in only
one way. Make sure the hole in the wedge nut is aligned
with the hole in the dish so the bolt can be installed (see
Figure 35).
2. Install the feed arm into the feed support socket on the
underside of the satellite dish. Since you may have the satel-
lite dish turned upside down in order to insert the feed arm,
take care to remember that your orientation is currently the
opposite of that shown in Figure 35.
3. Secure the feed arm with a 5/16-inch flat washer, 5/16-inch
lock washer, and 5/16-18 hex bolt. Use a torque wrench to
tighten the hex bolt 8 to 10 ft-lbs.
