Channel Power Monitoring
Simplify System Management. Amplify Uptime.
Managing a multi-channel radio system is tough enough. When performance degrades or outages occur, the clock is ticking—and the cost of delayed diagnosis can skyrocket, especially for remote or difficult-to-access sites.
Build Your Monitoring Network—One Smart Component at a Time
Choose from a range of directional and non-directional models to monitor forward power, reflected power, and VSWR—whether you’re measuring individual channels, composite signals, or inputs to your combiner.
Channel Power Monitor Display
3141
Centralizes data from your RF sensors — collecting, displaying, and logging it all in one place for a complete view of your network.
Channel Power Sensor
4042
Get per-channel power readings at the combiner output to instantly spot underperforming transmitters.
Composite Power Sensor
4043
Monitor the entire combiner output, detect antenna or feedline faults, and diagnose output-side issues with confidence.
Non-Directional Power Sensor
4044
Capture RF power from each transmitter for a clear snapshot of what’s being delivered to the system.

Need Help Choosing?
Make the right choice the first time—just share a few key details and we’ll match you with the perfect sensor.
Define Your Monitoring Need
Are you measuring transmit power, receive antenna health, or both? Do you need visibility per channel or for the entire system?
Know Your Frequency and Power Range
Share your operating frequency band(s) and the expected power levels at the monitoring point—this ensures the sensor is matched to your RF environment.
Describe Your System Setup
Tell us where the sensor will be placed (e.g., between combiner and antenna, at receive input), how many transmitters are involved, and if you require I/O or PTT integration.
From Small Sites to Smart Networks.
Ethernet-Based RF Monitoring
Not every site needs a full rack-mounted monitoring system. If you're working with a few radios, limited space, or just want a standalone setup—Bird’s Ethernet-based sensors deliver powerful insights without the extra infrastructure.
- No central processor required
- Web-based access via built-in Ethernet
- Scalable as your needs grow
Whether you're supporting a backup site, remote location, or smaller-scale network, Bird's Ethernet solutions offer a plug-and-play path to smarter RF monitoring—without overbuilding.
Remote Sites. Real Risks. Smarter Monitoring.
Certainty in Antenna Performance Starts Here
If uptime matters, your antenna is the point most likely to fail. VSWR problems, reflected power, and worn cables don’t raise flags—they just take your system down.
The best time to protect your system is before it fails. Bird equips you to catch problems early—and to adapt as your mission grows.
