4. Fit the two sections of the feed horn collar around the ridge at
the point where the feed horn meets the polarizer, as shown in
Figure 22.
5. Rotate the collar until it seats into the notch on the feed horn.
You must locate the notch before fully assembling the collar.
Failure to do so will result in damage to the polarizer
waveguide. When properly aligned, the two halves of the
collar will line up with the seam on the polarizer waveguide
as shown in Figure 23.
