Our series of Station Guardians provide critical monitoring and protection for transmission and antenna systems. These instruments simultaneously monitor and display both forward and reflected RF transmitted power and VSWR levels continuously on RF transmission lines. The system is equipped with both visual and alarms to warn of abnormal system conditions, and may be optionally equipped with switching relays to facilitate automatic standby switching.

The 410 series of indicators is mechanically similar to the SG-34 shown, except it contains the meter and switching circuits only. Both are available in a 19" rack-panel mount.
