Figure 26 shows how the TRIA is positioned for horizontal
transmit polarization compared to how it is positioned for
vertical transmit polarization.

6. Make sure the O-ring shown in Figure 25 on page 34 is in
place in the shim.
7. With the TRIA correctly positioned (rotated), place the
waveguide end plate against the shim.
8. Insert and tighten the four Allen screws.
At this point the radio assembly is ready to be installed.
