Interference Hurts Everyone...

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.

Interference can come from

  • Unauthorized transmitters
  • Faulty equipment
  • Poorly shielded installs
  • Almost anywhere...

A dedicated UI facilitates and guides you through signal triangulation on a map of your area. 

Is Bird’s Solution for You?

The SignalHawk-AOA works best for those who...

  • need a lightweight, portable spectrum analyzer.
  • are working in LMR, UHF/VHF, or frequencies up to 7.5 GHz.
  • are able to move around to triangulate a signal.
  • bring their own antenna tuned to the frequency of interest.


We might not be a great fit if you...

  • are hunting in the K, Ka, or higher bands.
  • need a permanent installation to alert on interference.
  • cannot receive a GPS signal while hunting.
The Experts Say

What is Interference?

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.

What is Interference Hunting?

Interference hunting is practice of tracking down unwanted RF sources, generally through triangulating where the RF energy is coming from.
