4042E-1-430513-0303

PTT Channel Power Sensor Monitor, 100 MHz to 1000 MHz, 500 W, IO Exp., Ethernet 4.3/10(F) - 4.3/10(F)

Smarter Antenna Monitoring for Maximum System Reliability

The Bird 4042E-1-430513-0303, Push-To-Talk Ethernet Channel Power Sensor Monitor is a high-performance RF power monitoring solution engineered for modern multi-channel environments. With 16 Push-To-Talk (PTT) inputs, expanded I/O, and secure Ethernet-based remote management, it delivers seamless integration and real-time insights.

Bird’s new Power Sensor Monitors provide reliable remote site monitoring to maximize uptime of mission critical communications. Unlike competitive solutions, 4042E RF Power Sensors can monitor for and alarm in the event of a reduced antenna VSWR. This provides an early warning of increased losses in the transmission line resulting from water ingress, damage, or deterioration.

Installed post-combiner, the 4042E Series can generate alarms according to pre-configured parameters for forward power and minimum/maximum VSWR, then communicated to users with SNMP traps. 4042E is a channelized power sensor allowing for the individual monitoring up to 16 radios.

Applications Highlights

• LMR Optimization – Measures power and VSWR at critical points, ensuring each channel performs within spec, even under heavy use.
• PTT-Driven Efficiency – Links alarms to transmitter activity across 16 PTT inputs, perfect for intermittent or emergency communications.
• Networked Deployment – Connects via Ethernet to central monitoring stations, supporting SNMP for automated alerts and multi-site management.
• Mismatch Detection – Tracks reflected power spikes and VSWR deviations, alerting operators to antenna mismatches or combiner faults that could degrade signal quality and disrupt LMR performance.
