Arcturus is a complete, turnkey solution providing protection and safety for multiplexed TV and FM antenna sites. The system is designed to serve multiple clients on shared antenna systems, while guarding important mutual assets.
Arcturus monitors key RF and environmental parameters including forward power, VSWR, line pressure and temperature. Rapid activation of transmitter interlocks in reaction to VSWR faults removes RF energy from the combiner and antenna system, minimizing the risk of loss or damage.
Predictive Analytics monitors and correlates key parameters, identifying abnormal trends before dangerous thresholds are reached. Maintenance can be scheduled to avert costly failures.
Arcturus hardware is based on ARC Plus technology proven in thousands of broadcast facilities. This high reliability platform has been extended to provide the ultimate in fast, dependable protection for combiners, transmission lines and antennas.
For stations using Burk AutoPilot®, Arcturus data may be integrated with transmitter data and included in studio or NOC displays.
Precision RF Sensor
Part #: PRF-1
The Precision RF Sensor produces scalable DC samples from any directional coupler, providing reliable forward and reflected power indications, permitting accurate VSWR calculation. The sensor connects to the directional coupler through a type “N” Connector and an included RF Pad*. Bring the sample into any remote control system, or use with the Plus-X VSWR for protection of antenna sites with Arcturus or ARC Plus. Each transmission line typically requires two RF sensors, one for forward power and one for reflected power.
Wide frequency response from 50 to 1000 MHz enables accurate measurement of individual transmitter outputs or multi-channel RF signals such as those found in combined antenna systems. The Precision RF Sensor accommodates signals with high or low peak to average ratios, making it suitable for both analog and digital power measurement.
The unit can be installed on any directional coupler equipped with a Type N connector, without the need for additional mounting hardware.
* Contact the factory for assistance selecting the appropriate RF pad value.

Line Voltage Sensor
Part #: LVS
Monitor AC Power Circuits
Each LVS monitors a single phase AC power circuit and provides a low-voltage DC output sample that tracks linearly with the AC input voltage. Additional LVS units can be added to monitor multi-phase AC power systems.
Save time and reduce wiring cost.
Now it’s easier than ever to connect to remote site equipment using SNMP Plus, the new optional SNMP manager inside the ARC Plus Touch or ARC Plus SL*. Integrate any SNMP-enabled device on your LAN or WAN with no additional wiring.
Monitor, display and log SNMP data in real time.
Map SNMP data directly to ARC Plus status and meter channels. Set alarm thresholds for fault detection. Respond automatically to changes in SNMP parameters using JetTM Active Flowcharts.
Manage alarms efficiently.
SNMP Traps, changes on SNMP status channels or threshold crossings on SNMP meter channels can be configured to generate email or SMS text alarm messages, or to make dial-out telephone calls using the Recordable Speech Interface, just like any other ARC Plus channel.
Take control with SNMP.
All the command and control capabilities of the ARC Plus Touch and ARC Plus SL can now be directed to your SNMP-enabled site equipment. Configure ARC Plus control channels to send SNMP “set” commands. Send commands to SNMP equipment on-the-fly using the ARC Plus smartphone interface. Combine SNMP with traditional parallel I/O in comprehensive automated functions.
Mix it up with SNMP Plus and Plus-X I/O.
SNMP-enabled devices at the transmitter site sit side-by-side with units that require parallel wiring for meters, status and control connections. Plus-X units let you distribute this I/O wherever it is needed in the broadcast facility or at other remote sites. ARC Plus connects to Plus-X units over the same LAN or WAN that it uses for SNMP communication, simplifying wiring and providing total facility control.
* Requires Version 5 ARC Plus Touch or ARC Plus SL.
Protect your RF Plant Investment
Plus-X VSWR protects your investment in RF combiners, transmission lines and antenna systems by fast activation of transmitter interlocks. The system monitors forward and reflected power on up to four transmission lines, continuously updating VSWR calculations, and takes immediate action when user-defined thresholds are exceeded.
