Broadcasting Signal Monitoring

Today, many major TV and radio stations share common antenna sites often with complex combining networks that demand monitoring and protection beyond a simple remote control. To protect these significant investments, broadcasters need a proactive solution to not only provide next level of monitoring, logging and control, but a comprehensive VSWR system for maximum protection. While most modern transmitter have VSWR protection they only protect the transmitter, leaving the rest of the system exposed to costly damage.

Stellar Eclipse with our exclusive VSWR Sentinel is designed to protect and monitor these systems by constantly monitoring the VSWR on all inputs and outputs to the combiner system, refreshing these values many times every second. Anytime a VSWR is detected that exceeds a preset threshold, hard relay interlock relays are controlled that can open interlocks on connected transmitters. RF power is then removed from the system when an unsafe condition exists, thereby saving the systems from costly damage.

Affordable Site Monitoring and VSWR protection for single or multiplexed TV and FM transmission systems
