The Bird 3170B Wattcher RF Monitor and Alarm System can automatically activate a variety of safety and equipment protection measures when it detects an abnormal antenna system load condition. The 3170B simultaneously displays forward and reflected power for 100 mW to 10 kW systems. Panel configuration consists of a line section complete with two QC-type N (female) connectors to insert in the coaxial transmission line.

The RF monitoring system can protect your transmitting equipment from damage and loss of air time when faults cause high-standing waves. It can warn a remote operator of low power due to detuning, component deterioration, or AC line difficulties and high reflected power due to factors such as antenna icing, transmission line problems, physical accidents and lighting strikes.

For power monitoring, each port of the 3170B must contain a plug-in element. Please note, elements are sold separately.

The 3170B requires two elements from tables 1, 2, 3, 4, or 6 of the document linked here. Elements can be accessed and purchased from the accessories section on this page.
