To ensure the best possible signal, avoid installing the CCU/Repeater or the remote
antennas in the following ways:
antennas in the following ways:
• Adjacent to or between tall buildings, signs, towers, or bridges.
• Near swaying limbs, branches, or cables that could strike and damage the antenna.
• Between, beneath, or near highway overpasses, elevated train platforms, or tunnels.
• Near objects or devices attached to the same pole.
• Within 500 feet of high power radio frequency (RF) transmitters (such as paging
• Near swaying limbs, branches, or cables that could strike and damage the antenna.
• Between, beneath, or near highway overpasses, elevated train platforms, or tunnels.
• Near objects or devices attached to the same pole.
• Within 500 feet of high power radio frequency (RF) transmitters (such as paging
transmitters, cellular transmitters, and municipal communications transmitters).
• Near potential broadband sources of radiated RF energy (such as power line
transformers, RADAR transmitters, cellular antennas, and neon or fluorescent signs).
• Inside metal enclosures (the antenna will not communicate if surrounded by metal) or
inside a building. The CCU/Repeater can be installed in a building or other metal
enclosure, but the antennas must be installed remotely.

Warning! Before installing a CCU/Repeater near or on the same pole as a
transformer, consult the National Electrical Safety Code (NESC), local utilities,
municipalities, and cable and telephone companies for recommended distances
from transformers and power lines.

AC Service Requirements
A 90 to 265 VAC 10A power source is required at the installation site for the
CCU/Repeater, unless you are using the DC CCU/Repeater or the solar CCU/Repeater. For
more information on these options, see

External Ethernet Connections
If the Ethernet connection is used as the communications backhaul, the CCU installation
site must have Ethernet access. Also, be sure to use weatherproof cables in this type of
installation.
site must have Ethernet access. Also, be sure to use weatherproof cables in this type of
installation.
Caution When using Ethernet as the communications backhaul, the CCU must be
identified as Ethernet-based when performing Initial Collector Setup (ICS). Failure
to do so prohibits the CCU from communicating with the Network Collection
Engine.

Remote Endpoint Antenna Placement
Antenna placement is one of the most important factors in determining your overall system
performance. Careful consideration must be given to proper antenna placement. Follow the
general guidelines below when determining the ideal location for a remote-mounted
endpoint antenna.

• The antenna needs to be mounted in a location where it has a clear unobstructed 360
degree view of the horizon.
