The feed support tube and the feed rods are the only main parts 
included in both antenna kits that are different.
Feed horn and waveguide 
transition
The feed horn (Figure 7) transmits and receives signals to and 
from the reflector. 
The J-type radio assembly requires a waveguide transition, as 
shown in Figure 7. In the antenna kit for the J-type radio, the 
transition is attached to the feed horn at the factory, as shown in 
Figure 7. As explained later in this manual, you attach the 
transition the radio assembly.
The antenna kit for the cradle-type radio does not include a 
waveguide transition because the feed horn attaches directly to 
the cradle-type radio assembly.

• Do not attempt to remove the feed horn window at  
any time.
• Be careful not to damage the feed horn window.
