Setting the radio polarization
Set polarization on the
1.Before proceeding, make sure the antenna polarization is set to 0°. See Setting polarization on page 63.
2.On the radio assembly, loosen the two screws at the top of the two circular brackets at each end of the transmitter. (Each of these brackets has a polarization scale.) See Figure 37.

To set polarization, align marker indicated by black arrow to the desired value on the scale. The setting in this photo is close to 0°.

3.Set the radio polarization to the calculated setting by rotating the radio and using the polarization scales on the circular brackets.
Plus ( + ) and ( – ) minus signs at the top of each scale indicate positive or negative values. Make sure you read the correct scale.
4.Tighten the two screws on the circular bracket.
This completes installation of the radio assembly.
