Antenna and Cable Monitor
ACM Series
Bird’s® Antenna & Cable Monitor is the solution for monitoring your RF transmission systems. Service providers
and self maintained end user’s can rely on this monitor and alarm to keep their critical sites up and running.
Designed to detect antenna and cable faults that transmitter-internal VSWR monitors may not detect, it also
provides accurate RF in-line power measurement functionality.
} Models available from 136-225 MHz, 225-520 MHz, 470-960 MHz, 960-2400 MHz Accurately monitors your antenna and
cable system VSWR levels.
} Integral coupler with high directivity optimizes measurement accuracy. Measures small changes in antenna VSWR with high
feeder and interface losses.
}
Provides multiple alarms if an antenna or cable failure should occur.
} Monitors transmitter output power and includes low or high power alarms.
}
Measures true average power of signals with high peak-to-average characteristics - works with any modulation!
}
Remote access with both monitoring and control via serial and ethernet interfaces.
} Included as standard Push-To-Talk (PTT) input to avoid false alarm triggering when the transmitter (radio) is not keyed.
