Installation Mode
The ODU can be installed on the antenna in two modes: direct mounting mode and separate
mounting mode.
Direct Mounting Mode
When the small-diameter and single-polarized antenna is used, the direct mounting mode is
usually adopted. In this case, if one ODU uses one antenna, the ODU should be installed at the
back of the antenna. If two ODUs share one antenna, one RF signal combiner-divider (hereinafter
referred to as hybrid coupler) should be added between the antenna and the ODU.
NOTE
Use a hybrid coupler adaptive to the XMC ODU if two ODUs are configured with only one antenna installed
in direct-mounting mode.
