4042E

Channel Ethernet Power Sensor Monitors


A powerful monitoring solution for smaller radio networks.


Maximize Up-Time


A powerful approach to antenna and power monitoring for smaller radio communications systems and paging networks. Designed for smaller sites where the Bird 3141 Channel Power Monitor would be underutilized, and connecting directly to the Internet or private IP network, they can be accessed remotely for both set-up and monitoring.

Bird’s 4042E Channelized Ethernet 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 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.
