2.1 Installing the ODU
The following sections describe how to install the ODU, including pole mounting
the ODU and connecting the cables.
2.1.1 Guidelines for Positioning the ODU
This section provides key guidelines for selecting the optimal installation locations
for the ODU See also Section 2.2.1 for guidelines on installing the antennas.
Select the optimal locations for the equipment using the following guidelines:
 The ODU is pole mounted. Its location should enable easy access to the unit
for installation and testing.
 When mounting several ODUs on a pole, make sure that at least one side of
the pole is clear, to enable easy access to all the ODUs.
 The ODU should be installed as close as possible to the antenna.
2.1.2 IF Cables
ODUs are connected to the AU (or to the ODU Power Feeder) via IF cables carrying
both signals and power. The maximum permitted attenuation of the IF cable at
applicable frequencies, its screening effectiveness and its maximum permitted DC
resistance (the sum of the DC resistance of the inner and outer conductors) are
provided in the following table.
CAUTION

and, wherever applicable, are licensed by the appropriate government regulatory authorities should
install outdoor units and antennas.
