REI ANDRE Advanced Near-field Detection Receiver Kit

No reviews yet Write a Review


REI's ANDRE is a handheld broadband receiver that detects known, unknown, illegal, disruptive, or interfering transmissions.

The ANDRE locates nearby RF, infrared, visible light, carrier current, and other types of transmitters. Quickly and discretely identify threats using the ANDRE Advanced Kit’s wide range of accessories specifically designed to receive transmissions across a 10 kHz to 6 GHz frequency range. Technical security specialists will appreciate the portability and responsiveness of the ANDRE. It is an excellent complement to an OSCOR Spectrum Analyzer as a preliminary non-alerting tool.

  • Efficiency: auto-recognition of attached probes displays the correlating frequency band
  • Usability: 3.5” touch screen display provides simple setup and operation
  • Portability: lightweight, handheld unit has a USB data port for file transfer

Andre Features

  • HISTOGRAM DISPLAY: The ANDRE features a signal strength histogram displaying RF levels over user-selected time intervals ranging from 5 seconds to 24 hours. Observe differences between digital, analog, and burst signals and set alert thresholds with audio and haptic feedback.
  • ZOOM VIEW: In zoom mode, only a 30 dB segment of the histogram is displayed. This reduced scale enables users to easily see small changes in RF signal activity.
  • SIGNAL INFORMATION AND BAND DETAILS: The ANDRE frequency counter automatically generates a signal list from the strongest signals. Signal frequencies are listed beginning with the strongest signal, and can be designated as threatening, friendly, or unknown. Double-tapping a signal provides more details including band classification information.
  • AUDIO MODE: The ANDRE can demodulate and playback live analog audio. Ten second audio files can be recorded, stored, and played back. The live audio screen displays a bar graph showing received signal strength.
  • POST-INVESTIGATION RESOURCES: Review time chart screenshots, playback demodulated audio, and review captured signal lists on a PC while writing your report.

Included Accessories

Probes & Antennas (9)

1. Whip Antenna
The Whip Antenna is a general purpose, near-field antenna used to locate RF transmitters from 30 MHz to 6 GHz.
Part Number: 6-00098

2. VLF Loop Antenna
The VLF Loop antenna is useful for analyzing the RF spectrum at low frequencies between 10 kHz and 30 MHz.
Part Number: 6-00102

3. Locator Probe
Operating between 20 MHz and 6 GHz, the locator probe's sensitivity is lower than other antennas and is used for locating an RF signal within a few inches.
Part Number: 6-00101

4. Concealed Antenna
Operating between 750 MHz and 6 GHz, the concealed antenna is used for covert detection of devices. When connected, the ANDRE will automatically switch to Covert Mode by automatically disabling any alerting features.
Part Number: 6-00100

5. Acoustic Leakage Detector
The ALD helps determine the vulnerability of acoustic leakage by placing the probe against structural objects such as walls or windows.
Part Number: 6-00094

6. Audio Transformer
The audio transformer test to see what, if any, audio is being transmitted down a physical telecommunication line between 300 Hz and 20 kHz.
Part Number: 6-00103

7. Carrier Current Probe
Tests for carrier current signals between 100 kHz to 60 MHz on any pair of conductors less than 250 volts.
Part Number: 6-00104

8. Log Periodic Antenna
Directional antenna that detects signals from 500 MHz to 6 GHz.
Part Number: 6-00105

9. Infrared/Visible Light Probe
This probe is built-in to the top of the ANDRE unit and detects transmissions from 1 kHz - 70 MHz. When no other probe is attached, this is the default ANDRE setting.
