RF interference can put critical communications, data transmission, and system reliability at risk. Whether you're protecting a mission-critical network or troubleshooting daily disruptions, you need to act fast—and with precision.

RF environments are more congested than ever. For public safety communications, cellular networks, distributed antenna systems, medical facilities, and everything in-between, you need to be able to identify the root cause issues quickly.

The Bird SignalHawk Series with Angle of Arrival (AOA) is built to help you identify and locate RF sources quickly whether your an expert or novice. A rugged, portable case allows you to easily cover distance and a dedicated mapping UI makes it clear where the signal is coming from.

Signal Interference occurs when an unwanted radio signal is present on your frequency of interest. When the carrier-to-interference ratio (C/I) is too low, your signal becomes drowned out by the unwanted RF power causing dropouts, missed signals, or general poor behavior. The exact C/I is dependent on your receiver and the nature of the interfering signal.
Interference hunting is practice of tracking down unwanted RF sources, generally through triangulating where the RF energy is coming from.
You can broadly break it into 3 steps:
The first step in hunting the unwanted signal is verifying its presence with a spectrum analyzer.
The SignalHawk-AOA guides you through determining the strength of your signal in every direction.
By repeatedly finding the signal direction at different points (generally 3-5), you can pinpoint your interferer.

AOA is also known as automatic direction finding. The Angle of Arrival is the direction from which the most RF power of the interfering signal is seen to come from. Performing an AOA measurement at multiple locations allows you to triangulate a source of RF energy.

Interference can come from almost any source of radio frequencies (RF). Faulty or poorly shielded electronics, damaged transmission lines, incorrectly configured transmitters, faulty Wi-Fi routers, knowing or unknowingly non-compliant devices, power supplies, transformers, jammers, improperly shielded medical equipment, etc. You can see why hunting interference is important!
Besides a SignalHawk-AOA, you will also need a directional antenna tuned to the interfering signal’s frequency. GPS reception is needed for direction information. A Wi-Fi connection is needed to download maps.
The longer you wait, the more interference costs you—in time, trust, and performance. Bird tools give you the power to act with certainty, solve fast, and stay in control. The interference hunting capability of the SignalHawk-AOA simplifies the process of finding, tracking, and solving unwanted RF signals.
