RF Filter Installation
This section describes installing a RF Filter to an existing pole-mounted CGR using the remote
antenna option. To install the CGR, refer to the CGR installation procedure in the Cisco 1240
Connected Grid Router Hardware Installation Guide.
Note: Depending on the geographic region where the CGR 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 installations in North America. See Australia
Applications.
Standard height remote antennas are mounted directly above the CGR (3–5 feet above the
CGR) and connected to the RF Filter with a remote RF cable. Remote antennas can be
mounted at an extended height above the CGR. The coaxial RF cable from the RF Filter to an
antenna mounted at an extended height will be locally sourced to the required length needed for
specific antenna mounting locations (½" superflex is recommended for extensions less than 35
feet).
This figure shows the remote antenna and RF filter connected to a CGR. Specifically, shows the
RF Cable, item 1, that connects between the RF Filter and the Antenna, the Lightning Arrestor,
item 2, the RF Filter, item 3 and the RF Cable, item 4, that connects between the CGR's N
Connector and the RF Filter.
