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.
