Signal Maintenance - On Track!

Ensure uninterrupted communication networks in the railway industry with Bird's innovative Railway RF Cable & Antenna Analyzer solution. Our comprehensive kit empowers technicians to maintain high-quality service networks, avoiding downtime and unnecessary expenses. Say goodbye to trial and error and optimize your communication infrastructure with ease.

Bird's Cable & Antenna Analyzer enhances reliability and ensures the maintainability of communication protocols in the railway space. Whether you're a novice or an expert user, our easy-to-use analyzer swiftly identifies and resolves issues before they become costly repairs.

The RailHawk® RF Railway Test Kit combines the functionality of the proven SiteHawk™ handheld analyzer, plug and play power sensor for UHF analog/digital radio systems, and GSM-R/LTE-R voice/data systems. All the necessary components are seamlessly integrated into a rugged transit case for convenience.


  • Test RF cables & antennas at the frequency of operation, not at DC where problems are masked.
  • Locate RF cable, connector & antenna problems at the source.
  • FDR (Frequency Domain Reflectometry) pinpoints faults at the frequency of operation, unlike other measurement techniques which can mask pending failures of critical system components.
  • Distance to Fault (DTF) mode can plot VSWR or Return Loss levels at each distance point along the cable and antenna system length.
  • Cable Loss function measures insertion loss of the cable system over a given frequency range.
  • OTG USB communication port for connection to Bird power sensors, storage devices and battery charging.
