PREPARING FEED ASSEMBLY
Adjust the scalar ring for the proper wave-guide setting according to the focal length chart on the next
page. Take the open end of the strut and slide it into the feed collar. Align the holes. Insert the ¼” x 1
½” bolts through the collar and strut, fasten with the ¼” nuts. Bolt the feedhorn onto the collar with ¼”
x ¾” bolts, not supplied by DH. Most feed have a 3-bolt pattern on the scalar just for attaching to the
collar.
Place the flatten end of the struts onto the antenna and use the bolts supplied (1/2” x 1 ½”) to fasten the
feed to the dish/mount. See diagram below. Use every other hole. Check with a focal finder to be sure
the feedhorn is at the proper focal length and pointed directly at the center of the antenna.
