Antenna and Cable Monitor with Alarm, 136-225 MHz, 100 Watt. 12 Vdc.

• BIRD's Antenna and Cable Monitor is the reliable solution for monitoring your RF transmission systems.
• Service providers and self-sufficient end users can rely on this monitor and alarm to keep their critical sites running.
• Designed to detect antenna and cable faults that the transmitter's internal VSWR monitors may not detect.
• An integral coupler with high directivity optimizes measurement accuracy.
• Measures small changes in antenna VSWR with high feeder and interface losses and provides accurate online RF power measurement functionality.

Product Features

• Provides multiple alarms if an antenna or cable fault occurs.
• Measures the true average power of signals with high peak-to-average characteristics; works with any modulation.
• Monitors transmitter output power and includes low or high power alarms.
• Remote access with monitoring and control via serial and Ethernet interfaces.
• It is included as a standard Push-To-Talk (PTT) input to prevent false alarms from being triggered when the transmitter (radio) is not activated.

Applications

• 3G
• Low power transmission.
• CDMA and CDMA 2000
• Edge
• GSM
• Microwave
• Pagination
• TDMA
• TETRA AND TETRAPOL
• VHF and UHF
