Tower Installation
TDC-0971-011 CCU 100 and Repeater 100 Installation Guide 39
Proprietary and Confidential
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).
