Details
Bird's Antenna & Cable Monitor is the solution for monitoring your transmission antenna
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 in-
line power measurement functionality.
