Lornet Non-linear Junction Detectors

Lornet non-linear detection

A Non-Linear Junction Detector (NLJD) is a counter-surveillance tool commonly used for detecting hidden transmitters or other electronic items. They work by transmitting an RF signal at the target location and displaying the received signal strengths of the detected harmonics. By comparing the received signal strengths, the operator can distinguish if the target location contains a dissimilar metal non-linear junction, such as some rusty nails, or an actual P-N junction, such as a diode or transistor.
