5-40 ODU MOUNTING
NWD-107460-02E Installation
For the antenna direct mounting of the ODU, following OMT is used.
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.
1 Fix the bracket and handle to the OMT,
Note Tightening torque is 3.0 N·m ± 10%.
