Important! To prevent exceeding the maximum EIRP set by the FCC and ISED,
there must be at least 2.2 dB of loss between the antenna connector at the base of the
tower cabinet and the high gain 915 MHz antenna. Do not exceed 3.5 dB of loss to
maintain system performance. Only use the Itron-approved high gain antenna.
Because of the size and weight of the Tower CCU, Itron recommends more than one person be
present for the installation.
For more information, see the Tower Enclosure CCU 100 Basic Installation Quick Reference
(TDC-0964-000).
Tower Installation Overview
The Tower CCU 100 (TCU) installation differs significantly from other CCU 100 installation
profiles in that the CCU 100 is installed within a cabinet enclosure at the base of a radio tower,
and all of the antennas are mounted externally and remotely. The standard cabinet protects the
hardware from adverse environmental conditions and provides easy access for servicing the
TCU and its related components.
The TCU may be installed in one of three configurations:
■
Pole mount. In this configuration, the TCU enclosure is attached to a large diameter pole
(3" to 12" diameter) with metal straps and pierced and slotted brackets (kit available from
Itron).
■
Pedestal mount. In this configuration, the TCU enclosure is mounted on a pedestal that is
bolted to a stable and secure surface (kit available from Itron).
