The feed support arm and the support 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
component, as shown in Figure 7. As shown in the figure, the
transition is attached to the feed horn at the factory. During
assembly, you attach the transition to the radio assembly. See
Chapter 3 – Assembling the antenna for more information.
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.
