Description
1 External GPS antenna
Receives GPS data from orbiting satellites. The cable
connection on the bottom of this antenna is TNC Female.
2 Mounting bracket
Attaches the antenna to your desired mounting location.
3 Antenna masts
Provide support for the GPS and WAN antennas. Cables for
each antenna are routed through the masts. Clamps on the front
of the mounting bracket secure the masts.
4 External WAN antenna (CCU only)
Provides the wide-area network (WAN) signal for the CCU.
The Repeater does not use this antenna. The cable connection

900 MHz Antenna
The 900 MHz antenna transmits and receives data messages from endpoints and repeaters
in the network.
There are three antennas that may be used for the 900 MHz radio link.
• A standard vertically polarized antenna that is directly attached to the CCU/Repeater.
• A standard vertically polarized antenna (5 dBi) that can be connected remotely.
• A high-gain vertically polarized remote antenna (8.15 dBi) that is mounted remotely
in place of the direct attached solution.
Remote antennas must be properly grounded during installation. When a remote antenna
is used, a lightning arrestor is supplied for this purpose.
