Easiest Way to Monitor RF Health Without Rolling a Truck

Ethernet-Enabled RF Monitoring Sensors

Targeted visibility. Smart alarms. No extra infrastructure.
Bird’s Ethernet-connected sensors give you channel-specific power and VSWR monitoring right at the source — without the need for a central controller. Whether you're tracking a single antenna, multiple transmitters, or composite signals, each sensor delivers reliable data via web interface and SNMP.

Why it matters:

Catch problems early with real-time alerts
Respond fast using remote access
Avoid costly truck rolls

Know What’s Happening—Before It Becomes a Problem

When RF systems fail, antennas are often blamed—but rarely monitored. Bird’s standalone Ethernet sensors change that. With real-time visibility into forward power, reflected power, and VSWR, you can catch performance issues like water intrusion, degraded cables, or failing transmitters before they take your system down.

Whether you need basic channel monitoring, composite power visibility, or false-alarm filtering with Push-To-Talk detection, Bird gives you data you can trust—without complex infrastructure or guesswork.

“How fast would I know if something starts to degrade?”

You’ll see the signs early—before signal drops or complaints roll in. These sensors detect real changes, not just full failures.

“What am I missing by not monitoring at the antenna?”

Plenty. Problems at the antenna often go unseen until it’s too late. Bird puts visibility where it matters most.

Can I reduce truck rolls with this setup?”

Absolutely. With real-time data and remote access, you can stop sending crews just to confirm signal status.

Why Choose Bird’s Ethernet RF Sensors?

Catch Problems at the Antenna—Before They Become Outages

Get instant visibility into forward power, reflected power, and VSWR. Bird’s Ethernet sensors flag early signs of failure, so you can act before it impacts system performance.

Why it matters:
Dropped calls and dead air aren’t the first sign of failure—just the most expensive. Bird helps you stay ahead of them.

Trust Every Alarm—No False Flags

With purpose-built alarm logic and optional Push-To-Talk detection, alerts only trigger during active transmissions—so your team responds to real problems, not background noise.

Why it matters:
False alarms waste time. Missed ones cost uptime. Bird filters out both.

See It All—From Wherever You Are

Built-in SNMP, web access, and per-channel visibility make these sensors powerful and easy to deploy—without complex infrastructure or custom platforms.

Why it matters:

When sites are remote and teams are lean, fast answers save real money.

RF Sensors: Which One Fits Your System Best?

Bird’s Ethernet Sensor Family gives you targeted tools to monitor antenna system performance—both transmit and receive—with confidence.

4042E

Precision monitoring for multi-channel transmit systems with Ethernet-enabled remote access and real-time alarms.

4042E PTT

Adds Push-To-Talk inputs to the 4042E platform, ensuring alarms activate only when radios are keyed. Plus built-in I/O.

4043E

Simplify transmit monitoring with composite forward and reflected power readings—ideal when channel-level detail isn’t needed, but reliability still is.

4046E-Coming Soon

Keep your receive path healthy with real-time VSWR and signal checks—no site visits, no signal disruption.

What to Know Before You Choose Your RF Monitoring Solution

To match your site with the right Bird channel power sensor, consider these key factors. The better we understand your system, the better we can help you monitor it — with precision.

Frequency Range

Bird’s sensors are designed for specific frequency bands. Knowing the frequency range of your radios ensures accurate power measurements and proper matching.

What to gather: Operating band(s) — VHF, UHF, 700/800/900 MHz, or others.

Transmit Power Levels

Different applications run at different power levels. This determines the appropriate sensor range for accurate readings without overloading or losing sensitivity.

What to gather: Typical and maximum forward power per radio.

Number of Channels / Radios

If you need to monitor multiple radios, you’ll want channelized monitoring to track each one individually — not just a single composite power measurement.

What to gather: Number of radios or transmit channels at the site.

Critical RF Checks You Might Be Missing

What part of my RF system is most likely to fail — and am I watching it?

When was the last time I caught a degradation before it caused downtime?

How confident am I that every transmitter at my site is pulling its weight?

I’ve got multiple radios — and no easy way to tell which one’s off.

I don’t need another system to babysit.

Sensor Selection Guide

Note: Part numbers end in -xxyy, where xx = RF input connector and yy = RF output connector.
Connectors must be from the same family — N, 4.3/10, or 7/16 DIN — and cannot be mixed.

You can’t fix what you can’t see.

Bird’s RF monitoring sensors give you real-time visibility into the health of your transmit and antenna systems — before small issues become big failures. Whether you need channel-level detail or site-level insight, you’ll know exactly what’s happening, and where to act.

It’s time to move from reactive troubleshooting to proactive insight — and let your team spend less time chasing problems and more time solving them.
