RailHawk RF Cable and Antenna Analyser Kit for Rail Applications

Bird’s Railway RF Cable & Antenna Analyser provides a comprehensive solution that allows technicians to maintain high-quality service networks in the railway industry.

Based on the need for redundant communications, Bird’s Cable & Antenna Analyser increases reliability and assures maintainability for communication protocols targeted in railway space. Designed to help novice and expert users, our easy-to-use analyser finds problems before they become time-consuming, expensive repairs.

Bird’s RailHawk RF Railway Test Kit is the result of combining the proven antenna and cable testing functionality of the SiteHawk handheld analyser and all the necessary loads, adapters and cables into a single rugged transit case.

Avoid communication shortfalls, downtime and expense resulting from trial and error of swapping components to fix your issue.

  • 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
