Hughes AN6-098P Feed horn and waveguide transition, Feed horn with protective packing material

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 The feed horn (Figure 7) transmits and receives signals to and transition 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.
