Installing the Remote Antenna
A remote antenna is required to ensure optimal radio performance when the CGR with a CAM3
is deployed in a Star configuration for communication with Battery Powered Devices (BPDs).
Standard height remote antennas are mounted directly above the CGR (3 to 5 feet above the
CGR). Remote antennas can also be mounted at an extended height above the CGR.
Note: Depending on the geographic region where the CGR with CAM3 is installed, a RF
filter may be required with a remote antenna. A RF filter is required for installations in
Australia, and other locations. A RF filter is not required for CAM3 installations in North
America. See RF Filter Installation.
Caution: The CAM3S is for Star deployments and uses the remote antenna . In
contrast, the CAM3M is for Mesh deployments and uses the WPAN antenna instead.
This is the only difference when is comes to deployment between the two devices.
Placement Guidelines for Remote Antenna
Antenna placement is one of the most important factors in determining overall system
performance. Careful consideration must be given to proper antenna placement. Follow these
general guidelines when determining the ideal location for a remote-mounted remote antenna:
■
Mount the antenna vertically.
■
Mount the antenna in a location where there is a clear, unobstructed, 360-degree view of the
horizon. The antenna receives and transmits in all directions. Objects such as building walls,
