TCS-805AH Fixed Radio Monitoring DF Station

TCS-805AH is used for long-term monitoring and DF of audio signals at fixed location and all-weather unattended working by remote control. It is suitable for the fixed use in key area and complex electromagnetic environment because of the high reliability and environmental adaptability.

Concealed Radio Monitoring & DF System


  • High sensitivity and wide dynamic range
  • Vertical/horizontal dual-polarized DF antenna array Bandwidth quick search of and narrowband accurate



  • Measure parameters of radio signals: frequency, frequency difference, level, field intensity, occupied bandwidth and modulation degree
  • Scan and monitor a designated frequency band, display spectrum diagrams and waterfall curves and conduct statistics to time occupancy
  • Scan and monitor multiple discrete frequencies, display spectrum diagrams and waterfall curves and conduct statistics to time occupancy
  • Demodulate, monitor and record radio signals and replay recorded audios

DF and location

  • Conduct DF to designated signals and draw direction indication lines on electronic map
  • Multi station joint direction positioning and real-time cross position.

Electronic map

  • Support kinds of Electronic map, such as Maplnfo and MGS (source of map provided by users
  • Zoom in and out, roll, fully disclose, add or delete icons and words and display the azimuth and cross location of the measured signal

New signal warning

  • Generate electromagnetic spectrum background signal sample during frequency band scanning
  • Warn when new signal be found

Remote control

  • Via LAN port, collect and store monitoring data on the CS­ RM & DF application software
  • Power on/off the equipment and monitor the environment of equipment room remotely: smoke, door & window displacement, voltage, current, temperature, humidity and room video image
