Installing the feed
support tube Install the feed rods and feed support tube as explained in the
following two sections. These instructions apply to both types of
feed support tubes and feed rods, that is, the tube and feed rods
for the J-type radio or cradle-type radio.
Attaching the feed rods Attach the feed rods to the reflector:
1. Attach the feed rods to the rim of the reflector as shown in
Figure 18.
The feed rod end with the longer flat part attaches to the
reflector rim; the end with the shorter flat part attaches to the
feed support tube (as shown in Figure 19 on page 28).
Point the lower end of each feed rod inward, toward the space
in front of the lower part of the reflector. When both feed 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 tube and feed 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 Installer Support to obtain the correct
parts.

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