Proprietary and Confidential
This chapter describes how to prepare for a collector or repeater installation.
Installation Profiles
You can install the collector or repeater in a variety of configurations and locations.
Depending on the installation location, you can:
• Install the CCU or repeater components in the same location (as an integrated
solution). This is the recommended configuration.
• Install the GPS/WAN antennas externally from the collector or repeater.
• Install the 900 MHz antenna remotely (as a distributed solution).
For example, you can install the collector or repeater at the base of a water tower, mount
the external GPS/WAN antenna system further away for optimum reception, and place the
900 MHz antenna at the top of the water tower.
The following profiles were identified for CCU installation.
Location
Description
Utility pole The collector or repeater is installed on a utility pole. Mount the collector or
repeater as high as possible on the pole for optimum reception.
Light pole The collector or repeater is installed on either a light pole or the davit arm
that extends from the light pole. Mount the collector or repeater as high as
possible on the pole for optimum reception.
Outdoor wall or pipe with remote
900 MHz antenna
The collector or repeater is installed on an outside wall or pipe with the
900 MHz antenna remotely mounted to achieve the maximum elevation
and reception.
Indoor wall or pipe with remote
900 MHz antenna and external
GPS/WAN antennas
The collector or repeater is installed inside an equipment room with the
900 MHz antenna remotely mounted to achieve maximum elevation and
reception. The WAN (or other digital cellular) and GPS antenna are
externally mounted to provide acceptable coverage.
Pipe or mast The collector or repeater is secured to a pipe or fence railing (from 2 to 3.5
inches in diameter). This type of installation typically occurs on the tops of
water towers.
For more information about these profiles, as well as the Itron-recommended profile, see
Installing the CCU/Repeater on page 19.
Siting Collectors or Repeaters
Collectors or repeaters are installed in the field on a variety of surfaces, such as wooden
or metal walls, metal pipes, fence railing, and utility poles.
