There are five possible antennas (two direct attached antennas and three remote antennas)
that may be used for the endpoint radio link.
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.
