Once the radio assembly is removed from the feed arm, remove the four Allen screws that attach
the feed horn to the horizontal shim and TRIA (Transmit Receive Isolation Assembly). See
Figure 24. Figure 25 shows the orientation of the TRIA with a horizontal shim attached. The
TRIA would be rotated 90 degrees if a vertical shim were attached.
