Setting the radio
polarization
Set polarization on the cradle-type radio as follows:
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.
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.
