Siting CCUs/Repeaters
CCU 100 and Repeater 100 Installation Guide 9
Proprietary and Confidential
To ensure the best possible signal, avoid installing the CCU/Repeater or the external
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
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 antennas 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 externally.
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 Mains Power Installation Profiles on page 13
or Solar Power Installation Profiles on page 43.
External Ethernet Connections
If the Ethernet 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.
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.
