Adjusting transmit
circular polarization
It may be necessary 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 currently set for LHCP or RHCP by the way it leans.
(See Figure 19.)

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