Precise bugging detector - RFD-5

ELBI Electronics' RFD-5 is a broadband radio transmission detector with very high sensitivity and wide dynamic range. The precise bugging detector is optimised for professional detection and localisation of radio listening devices utilising transmission band up to 25GHz, both analogue and digitally modulated.

Advanced signal processing algorithms allow to detect even short-term transmissions and store peak levels in memory. Built-in interference filters of the bugging detector and storing of background signals allow to reduce the number of false alarms and to increase the effectiveness and accuracy of RFD-5 detector's operation. The device features also an audio demodulation function, and indication of signal strength with audible clicks, which allows to facilitate the operation during localisation of a transmission source. The memory can store information about suspicious signals for analysis later on – up to 16 events, together with information on time of recording. The radio transmission detector is lightweight and mobile, sporting a telescopic antenna, maximum length 37cm. The RFD-5 bugging detector is powered with 9V 6F22 batteries (regular or rechargeable). A sturdy, metal housing effectively protects the device against mechanical damage.

Main assets of RFD-5 precise bugging detector

  • Precise detection - very high sensitivity and wide dynamic range.
  • Supported frequency range up to 25GHz.
  • Peak level memory - detection of pulse transmissions.
  • Advanced interference filtering.
  • Audio signal demodulation.
  • Acoustic indication of signal strength - Geiger clicks.
  • 4 ways of signal strength indication - bar indicator, numerical indicator, delayed bar indicator, peak indicator.
  • Detection of radio signals of any type - including digitally encoded signals.
  • Detection of wideband, pulse and hopping transmissions.
  • Detection of cell phones and other devices utilising digital telecommunication network transmissions.
  • Permanent protection due to recording of detected events for further threat assessment (including detection time and signal level).
  • Background signals elimination, increasing efficiency of operation.
  • Possibility to calculate signal strength and estimated distance from its source.
  • Efficient power management of the precise bugging detector allows for prolonged operation.
