Adjusting transmit
circular polarization
It may be necessary for you to reposition the polarizer waveguide
on the radio assembly to set the proper polarization between the
radio transmitter and the antenna reflector. Before proceeding
with the installation, check the installation reference sheet to
determine whether the installation calls for left-hand circular
polarization (LHCP) or right-hand circular polarization (RHCP).
Once you determine which polarization setting is required, check
the position of the polarizer waveguide to determine whether an
adjustment is necessary. From the rear of the radio, looking
toward the reflector, you can easily determine whether the
polarizer is set for LHCP or RHCP by the way it leans. (See
Figure 15.)

Note:
There is no default factory setting for transmit
polarization. Radios can be shipped with either setting.
