Lornet-36 Non-Linear Junction Detector

Listed in Non Linear Junction Detectors

A non-linear junction detector Lornet-36 is an indispensable tool for a quick and reliable location of unauthorized electronic devices during investigation operations in premises with a high density of electronic equipment.

It is very efficient when it comes to identify miniaturized electronic devices (10x20mm) at a considerable distance, which is sometimes crucial. For instance, a suspicious object has to be analyzed within a safe distance. Moreover, the use of a super high signal frequency range gives Lornet-36 some unique capabilities of detecting semiconductors covered by various materials. It can also detect devices through slits and holes, ungrounded shielding, etc.

Built on a very high probing signal frequency and narrow antenna directional pattern makes the NL JD Lornet-36 a dramatically superior to any competing gadget in the industry in terms of detection range, selectivity and positioning accuracy.

This model can even detect a location of cell phone's SIM card within a distance of 1 meter.

  • 2d and 3d harmonics sensitivity (antenna gain not considered) -110 dBm
  • Dynamic range > 40 dB
  • Antenna directional pattern width (at 1st/ 2d/ 3d harmonic) 16/ 8/ 4 degrees
  • Time of continuous operation at the maximum probing power 3,0 hours
  • Dimensions in operational / shipping condition 477х303х227 /303х303х230 mm

Main competitive advantages:

  • Lornet-36 has a three times wider detection range compared to competitors (for example, NGO ORION).
  • Lornet-36 has no analogues in selective checkings of a suspicious object from the distance of 5-10 meters.
  • A very narrow directional pattern of the antenna and a built-in pinpointing laser provide a space selective detection of various semiconductor elements with a high precision, making it very convenient to use.
  • With an interval less than 30 cm between mark points analogous competing devices cannot locate a 3 harmonics simulator because of the masking interference of a 2 harmonics simulator, whereas Lornet-36 can locate and select both mark points at the distance of over 1 meter.
  • The device features an innovative technology and is made of high quality materials. Furthermore, it has a very ergonomic design: compact, lightweight and is easy-to-use.
  • The electromagnetic effect upon the operator is kept at the minimum level due to a very low duty cycle of probing pulses and decreased radiation on the side of operator.
  • The device uses wireless headphones, what gives the operator free hands.
  • Detector has a laser lightning for pointing a center of detection area
