Coaxial Cable
When remote mounting the antennas, coaxial cable must be supplied to connect the antenna
to the CCU/Repeater. The proper size of cable is dependent on 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. Coaxial cable systems must be installed according to the manufacturer's
specifications. Itron recommends using qualified radio installation contractors to install the
remote antenna system. See Motorola R56 guidelines for recommended practices on cable
installation.

Cable lengths should not exceed 12 feet, except when used with the high-gain antenna.
Remote Mount Endpoint Antenna on a Standard CCU/Repeater
When selecting cable for the remote mount unity gain endpoint antenna on the standard
(non-tower) CCU/Repeater, total cable loss cannot exceed 1.5 dB to maintain system
performance. Allow 0.1 dB loss for each connector.

Remote Mount High Gain (8.15 dBi) Endpointed Antenna on a Tower CCU
When selecting cable for the remote mount high gain (8.15 dBi) endpoint antenna on the
tower CCU, total calculated loss between the tower cabinet and the antenna must be greater
than 2 dB, but less than 3.5 dB.

Allow 0.1 dB loss for each connector. If required, a 1 dB attenuator (similar to the
Pasternack PE7002-1) may be used to attain the desired power at the antenna.
