11.10 ADJUSTING TRANSMIT CIRCULAR POLARIZATION
(TRANSMIT POLARIZATION) Spaceway System.
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, check the
installation reference sheet to determine whether the installation calls for left-hand circular polarization
(LHCP) or right-hand circular polarization (RHCP). This is transmit polarization not receive.
Once you determine which polarization setting
is required, check the position of the polarizer
waveguide on the radio 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 17.)
