Installing the feed
support arm
Install the support rods and feed support arm as explained in the
following two sections. These instructions apply to both types of
feed support arms and support rods for both the J-type and the
cradle-type radio.
Attaching the support rods
Attach the support rods to the reflector:
1. Attach the support rods to the rim of the reflector as shown in
Figure 16.
The support rod end with the longer flat part attaches to the
reflector rim; the end with the shorter flat part attaches to the
feed support arm (as shown in Figure 17 on page 26).
Point the lower end of each support rod inward, toward the
space in front of the lower part of the reflector. When both
support rods are correctly installed, their lower ends are just a
few inches apart.
2. Tighten each nut just enough to keep the hardware in place.
Note:
If you are installing an antenna that will use a cradle-type
radio assembly, make sure the feed support arm and support rods
are stamped TG. (Other letters or numbers may appear with TG.) If
these parts are not stamped TG, they are the wrong parts for the
cradle-type radio. Contact your distributor or installation manager
to obtain the correct parts.

Note:
The photos in this section show the feed support arm
and support rods for the J-type radio. These parts for the
cradle-type radio are very similar and are installed in the same
way.
