Procedure for Radio Waves Rotator
The polarization rotator is fixed by three metric Allen-head bolts.
To change the polarization of the Radio Waves antenna:
1. Loosen the bolts. Refer to Figure 2-7.
2. Rotate to other end of the slots. Refer to Figure 2-7.
3. Check bolt heads are located in the slot recesses.
4. Refasten.
Figure 2-7 shows a close-up of the polarization rotator being released from the
vertical position (left) and rotated clockwise towards horizontal (right).
The ODU must be mounted on the collar to match the chosen polarization.
Correct positioning for vertical or horizontal polarization is shown in Figure 2-8.
