Cautions:
1. For connecting the OMT to the antenna, the circular type waveguide flange
of the antenna is applied to the system. When the V/H flange is mounted to
the antenna, it must be changed to a circular type.
2. When mounting the ODU to the OMT, confirm the polarization for Main
Master and SUB Master ODU. The installation of the corresponding ODUs
in the opposite station must have the same polarization in order to make
into line Main Master and SUB Master MODEMs.
