Installation Guide

interference and any effects it may have on system performance. Consult your Itron systems
engineer for more information.
■
Height is preferred for optimal performance. Itron recommends installing the antenna no
higher than 30 meters.
Caution: Do not install a 5.5/5.15 dBi antenna directly on the CGR. Antenna
installation directly on the CGR will compromise mechanical integrity and will not meet
the compliance requirements. See 915MHz 5.5dBi Remote Antenna Kit and
915MHz 5.15dBi Remote Antenna Kit.
Caution: Do not install a 8.15 dBi antenna directly on the CGR. Antenna installation
directly on the CGR will compromise mechanical integrity and will not meet the
compliance requirement for a loss of 2.2dB (for any exceptions, ensure you read this
entire section), between the RF filter and the 8.15 dBi antenna. See 915MHz 8.15dBi
High Gain Remote Antenna Kit 915MHz 8.15dBi High Gain Remote Antenna
Kit .
A side arm antenna installation must be done if the antenna is mounted where it does not have
an unobstructed 360-degree view. Refer to the following guidelines for a side arm antenna
installation:
■
The minimum standoff distance is 60 centimeters, where the interfering structural members
are 10 centimeters or less in diameter and spaced more than two meters apart.
■
For structural members between 10 and 25 centimeters in diameter, use a sliding scale of
0.6 to 1.5 meters. (For example, a 60-centimeter standoff at 10-centimeter diameter to a
150-centimeter standoff at 25-centimeter member diameter.)
Connecting a RF Filter
1. Connect one end of the RF Cable, see item 2, coming from the RF Filter to the N Connector,
see item 1, located on the bottom of the CGR enclosure.
