1.2 Installation Mode
Different installation modes are available for an ODU, depending on the type of antenna
configuration.
There are two methods of mounting the ODU and the antenna: direct mounting and separate
mounting.
l The direct mounting method is normally adopted when a small-diameter and single-
polarized antenna is used. In this situation, if one ODU is configured for one antenna, the
ODU is directly mounted at the back of the antenna. If two ODUs are configured for one
antenna, an RF signal combiner/splitter (hereinafter referred to as a hybrid coupler) must
be mounted to connect the ODUs to the antenna. Figure 1-1 shows the direct mounting
method.
