High-speed RF fault detection to protect combiners, transmission lines and antenna systems. The Plus-X VSWR monitors forward and reflected power on one to four transmission lines, continuously recalculates VSWR, and trips transmitter interlocks immediately when a user-defined threshold is exceeded.
It runs fully autonomously, so protection continues even if the connection to the remote control is lost, and its fault-tolerant design uses redundant relay outputs for reliable interlocks. It works standalone or with an ARC Plus or Arcturus system over Ethernet, and units can be cascaded with a dedicated status input and redundant relay pair. Pair it with Burk PRF-1 Precision RF Sensors (two per line, forward and reflected).
