Endpoint Antenna
The Endpoint antenna transmits and receives data messages from endpoints and repeaters in
the network.
There are five possible antennas (two direct attached antennas and three remote antennas)
that may be used for the endpoint radio link.
• A standard vertically or horizontally polarized antenna that is directly attached to the
CCU/Repeater.
• A standard vertically or horizontally polarized antenna that can be connected
remotely, in place of the direct attached solution.
• A high-gain vertically polarized remote antenna (8.15dBi) that is mounted remotely in
place of the direct attached solution. This antenna is only approved for the Tower
CCU with proper cable loss to meet FCC regulations.
• Remote antennas must be properly grounded during installation. When a remote
antenna is used, a lightning arrestor is supplied for this purpose.
• The remote antenna's maximum allowed installation height above ground is 100 feet.
Installation heights are determined by RF propagation studies by Itron systems
engineering. If additional height is needed for the antenna, the tower version of the
CCU is recommended.
• Coaxial cable used to connect the endpoint antenna to the CCU/Receiver must be
properly grounded. See Lightning Arrestor on page 11 for more information.
• All coaxial cable connections must be properly weather-proofed per industry
standards, unless otherwise specified. If the CCU/Repeater is installed indoors, only
the connections located outside need to be weather-proofed.
When the CCU/Repeater is ordered with a remote antenna kit, some associated mounting
hardware is included. Coaxial cables for the remote antennas are not included in the kit.
These cables must be provided by the installer. Please see Coaxial Cable on page 13 for
coaxial cable specifications.
