Proprietary and Confidential
DC Mains Power
DC wiring to the collector or repeater utilizes a two conductor cable. Connect the CCU to
a 10A DC circuit breaker or fuse. Wire the Itron-supplied two conductor cable by
attaching the red wire to a +12V source. Attach the black wire to ground.
Materials Not Provided by Itron
The following materials are not provided by Itron in the collector or repeater kit, but are
required for installation.
Please acquire these items prior to beginning an installation.
• Coaxial cable on page 14 (for remote/external antennas)
• Connectors on page 16
• Mounting hardware on page 16
Coaxial Cable
When you are mounting the remote/external antennas, you must supply coaxial cable to
connect the antenna to the collector or repeater. The required cable size is dependent on
the total cable length and frequency. Coaxial cable also requires proper hoisting grips,
ground kits, connectors, jumpers, hangers, and weather proofing material. Coaxial cable
and accessories are not provided by Itron. You must install and test coaxial cable systems
according to the manufacturer's specifications. Itron recommends using qualified radio
installation contractors to install and test the remote/external antenna system.
All coaxial cable connections must be properly weather-proofed per industry standards
unless otherwise specified. This includes any connections for the antennas and the
collector or repeater.
Refer to Antenna and Line Sweeps Procedure on page 83 to verify that the coax and
antenna are correctly installed.
Remote Mount Standard (5.15) dBi 900 MHz Antenna on a Standard
CCU/Repeater
When selecting cable for the remote mount 900 MHz antenna on the standard (non-tower)
collector or repeater, total cable loss cannot exceed 1.5 dB to maintain system
performance. Allow 0.1 dB loss for each connector.
