Figure 20: Adjusting circular polarization (collar removed)
3. After making the adjustment, reseat the waveguide with the
TRIA and reassemble the collar as follows:
Fit the two halves of the collar around the waveguide as
shown in Figure 21 so that the notches in the collar come
together around the ridge formed at the waveguide seam.
When properly aligned, the seam formed by the two halves of
the collar will line up with the seam on the waveguide.
4. Reinsert the two Allen screws into the collar and tighten to
secure the polarizer in place. Be sure to tighten the collar
completely.
NOTICE
You must assemble the collar exactly as described above and as
shown in Figure 21. Failure to do so could allow moisture to
accumulate inside the TRIA, causing damage to the radio.
