The most commonly used antenna included with the ANDRE Near-field Detection Receiver is the Whip antenna. It is significantly larger than the other antennas and is an effective general-use antenna for locating RF signals. In this article, we will dig into how the whip antenna is designed and why it is considered the more commonly used antenna in the kit.

A whip antenna is a basic antenna design, typically consisting of a straight, flexible wire or rod connected to a receiver. Shown in the picture is the Standard RF Probe from the CPM-700 Deluxe, which is a traditional whip antenna. When the CPM-700 and ANDRE antennas are viewed side by side, it’s obvious the ANDRE antenna is a very different design. Continue reading “ANDRE Whip Antenna: Simple Enhanced Design”

New additions are coming to the handheld ANDRE Near-field Detection Receiver. REI is pleased to announce the ANDRE Deluxe featuring three new antenna attachments and a variety of accessories to make your investigations easier and more effective.

New antenna extends frequency detection range to 12 GHz

ANDRE Deluxe TripodCOOKEVILLE, TN – June, 2018 — Research Electronics International (REI), a leading manufacturer of counter-surveillance equipment, announces the release of the ANDRE Deluxe Near-Field Detection Receiver. The ANDRE detects signal activity and displays a histogram of signal strength over time. It is a handheld broadband receiver capable of detecting covert electronics including GSM bugs, microphones, cameras, RF and Wi-Fi transmitters, and mobile phones. Applications may include:

  • RF emissions detection
  • Prison contraband
  • RF spectrum management
  • Executive protection
  • Technical surveillance countermeasures (TSCM)
  • Intelligence protection
  • Fraud detection at exam testing sites

The ANDRE’s success at detecting and locating the source of RF, infrared, visible light, carrier current and other types of transmissions has expanded in the new Deluxe model with several additional antennas/probes, accessories, software and operational features.

Integrated Spectrum Analyzers like OSCOR combine capabilities from multiple types of analyzers to locate signals, not just detect them.

In the last few decades, the volume of RF spectrum activity has exploded and shows no indication of slowing as the demand for wireless information transmission grows insatiably. The opportunity to use free airspace for good is equal to the ability for it to be used nefariously. RF safety and security efforts will face significant challenges in coming years to keep pace with increased opportunity for abuse.

One particular area of RF exploitation that is demonstrating significant expansion is illicit surveillance. Availability of cheaper and highly advanced surveillance products at the consumer level has taken technology that was once reserved for an elite field of intelligence specialists, and made it accessible to the average individual. Easy to use video and audio recording transmitters can be disguised and hidden in the most common, ordinary off the shelf products. These malicious devices are being produced in volume and marketed commercially with little restriction. A quick search for “hidden camera” on your favorite online retailer site may yield surprising results.

REI’s CPM-700 was the standard in RF broadband detection for over 20 years in the TSCM market. Now the ANDRE offers many more features to its users. The ANDRE includes robust tools to help identify what type of signals are being encountered and offers powerful post-sweep analysis functions not available in other broadband detectors.

HOW THE SIGNAL LIST WORKS

The ANDRE automatically generates a list of detected signals that exceed the designated trigger level and register on the frequency counter. These signals display from strongest initial RF level at the top to weakest at the bottom and can be customized to show 10, 25, 50, or 250 signals. Even when the signal list display is full, the ANDRE continues to capture weaker signal information. If a newly-detected signal is stronger than another in the list, the list automatically re-sorts and weaker signals roll off.

The newly-launched ANDRE Advanced Near-field Detection Receiver from Research Electronics International is helping prevent fraud at exam testing sites. Commonly used for counter surveillance operations and intelligence protection, the ANDRE is now also helping educators prevent cheating during examinations by detecting covert electronic transmissions.

According to news reports out of Brazil*, eleven individuals were arrested last year for using electronic devices during the high-profile National High School Examination (ENEM). This year, the Ministry of Education will be using ANDRE to locate and identify participants who attempt to use electronic devices during the exam and may have circumvented inspection by metal detectors.

FOR IMMEDIATE RELEASE:

Research Electronics International (REI) is pleased to announce the ANDRE™ Advanced Near-field Detection Receiver, a hand-held broadband receiver that detects and assists in locating nearby RF, infrared, visible light, carrier current and other types of transmitters.

ANDRE Advanced Near-field Detection Receiver Front ViewThe ANDRE detects signal activity in its vicinity and displays changes in signal strength over time, allowing users to quickly locate the source of transmissions. The ANDREs frequency counter provides quick identification of the signal frequency and outputs additional information to an automatic signal list generator.

Antenna probes included with the ANDRE can be used to sweep rooms and objects in search for known, unknown, illegal, disruptive, or interfering transmitters from 10 kHz to 6 GHz.

A 3.5 inch touch screen displays all of the operation controls and frequency activity. The frequency chart provides advantages over other RF detectors by showing rising and falling signal strength over time. Eight displayed time intervals can be selected ranging from 5 seconds to 24 hours. This helps identify pulsing signals and shows historical peaks, to ensure nothing will be missed. Manual and automatic threshold settings notify the user when a signal exceeds defined strength levels with haptic, audible, and visual alerts.
