Installing connectorized antennas
Installing connectorized antennas
If the ODU is connectorized, perform this task to install separate antenna(s).
Preparing for connectorized installations
Before proceeding with the installation, perform the following checks:
•
Check that the correct components are available, as described in
on page 2-24.
•
Check that the selected antenna conforms to the applicable regulatory restrictions, as
described in
regulations
•
Check that the correct tools are available. The tools required for mounting the
antennas are specific to the antenna chosen. Refer to the antenna manufacturer's
instructions.
Mounting and connecting antennas
To mount and connect the antenna(s), proceed as follows:
1
Mount the antenna(s) according to manufacturer's instructions. When using
separate antennas to achieve spatial diversity, mount one with Horizontal
polarization and the other with Vertical polarization.
2
Connect the ODU to the antenna with cables of type LMR100, LMR200, LMR300,
LMR400 or LMR600. Connect the ODU 'V' interface to the vertical polarization
antenna and connect the ODU 'H interface to the horizontal polarization antenna
(Figure
When using separate antennas to achieve spatial diversity, the antenna cables
will be disconnected from the ODU during the alignment procedure. Therefore,
do not weatherproof the ODU joints until antenna alignment is complete.
3
Where the ODU is mounted indoors, install lightning arrestors at the building

4
When dressing the antenna cables, form drip loops near the lower ends. These
ensure that water is not constantly channeled towards the connectors.
