Cable & Antenna Analyzers for Railroad Communication Systems

Locate RF cable, connector & antenna problems at the source


Smart railway systems require the use of critical communications for operation and control, and to improve performance, reliability, and passenger experience. However, rain, snow and extreme temperatures can cause transponders to fail, cables to experience water ingress and antennas to be damaged from objects thrown from the rail bed.

SK-4500-TC, 1 MHz-4.5 GHz Antenna and Cable Analyzer & SiteHawk Test Kits    

SiteHawk™ Cable and Antenna analyzers are the most cost-effective solution to quickly identify failing RF cables, connectors and antennas over thousands of railway miles and numerous locomotives.

The handheld testers offer measurements that include precision return loss vs. frequency, return loss vs. distance, voltage standing wave ratio (VSWR), cable loss and distance-to-fault (DTF) measurements.

SiteHawk™ analyzers help novice and expert users alike find problems before they become time-consuming, expensive repairs of the:

  • Positive Train Control system
  • Train-to-Infrastructure communication systems
  • Interwagon communications
  • Intrawagon communications
