If the radio assembly is already attached to the feed arm, skip this 
section and go to Connecting the feed arm to the antenna 
reflector on page 26.

Follow these steps to install the radio assembly on the feed arm:

1. Place the O-ring in the circular depression in the square end 

of the feed arm. See see Figure 23. 

2. Align the square end of the radio assembly with the square 

end of the feed arm so you can install the four M4 screws. 
Install the lock washers on the screws. Use the Allen wrench 
to install the M4 Allen screws, but do not fully tighten them.

3. Align the bolt holes on the top of the transmitter with the bolt 

holes on the bottom of the feed arm.

4. Install the 5/16-18 bolts in the aligned holes. Finger tighten 

them; do not tighten them further at this time.

5. Use the Allen wrench to tighten the Allen screws.
