- Model: LORNET-36
The Lornet 36 is a parabolic nonlinear junction detector built for stand-off TSCM sweeps where you cannot stay close to the target surface. Its 3.6 GHz parabolic antenna and narrow 16° beam focus energy onto a small area so operators can check walls, ceilings, equipment housings and structural elements at distances of up to about 10 m, then confirm the point of interest using the integrated laser pointer.
Dual-harmonic operation, selectable pulse and continuous-wave (CW) modes and automatic channel selection with anti-jamming DSP support reliable detection of electronic components that contain semiconductor junctions, including devices that are powered down or only active intermittently. A handheld form factor, Li-Ion battery power and wireless audio monitoring via the supplied headset make the Lornet 36 practical for mobile TSCM teams working across multiple rooms or sites.
Key Features & Benefits
- Parabolic 3.6 GHz beam: Narrow 16° parabolic pattern concentrates RF energy for long-range checks of walls, ceilings and equipment from a safe distance.
- Stand-off TSCM sweeps: Remote detection capability up to around 10 m helps teams inspect high, exposed or sensitive areas without climbing or approaching the surface.
- Dual-harmonic nonlinear detection: Reception of second and third harmonics supports verification that a response is caused by electronic components rather than benign materials.
- Pulse and CW operating modes: Pulse mode supports faster area coverage, while CW mode provides more detailed acoustic and visual feedback on a specific location.
- Automatic channels and anti-jamming DSP: Automatic selection among three preset bands and digital filtering help maintain usable channels in noisy RF environments.
- Laser-guided targeting: Built-in laser indication marks the beam centre so operators can correlate signal changes with a precise point on the surface under inspection.
- Wireless audio monitoring: The supplied wireless headset with radio receiver allows operators to listen to harmonic responses while maintaining freedom of movement during a sweep.
Where the Lornet 36 Works Best
The Lornet 36 is aimed at professional TSCM teams, corporate security departments and government agencies that need to locate hidden electronics at a distance or in locations that are difficult to reach. It adds stand-off nonlinear detection to programmes that already use close-range NLJDs and RF tools.
- Executive offices and boardrooms: Check walls, ceiling panels, decorative elements and fixtures from across the room before high-level meetings.
- High ceilings and structural elements: Inspect beams, ceiling junctions and overhead routes where installing access or lifting equipment is not practical.
- Secure facilities and critical infrastructure: Perform stand-off checks of doors, enclosures, conduits and mounted equipment without touching sensitive surfaces.
- Vehicles and transport assets: Scan vehicle exteriors, cargo areas and bodywork sections at a distance before moving to closer inspection where needed.
How the Parabolic NLJD Supports Stand-Off Detection
Unlike standard RF bug detectors that rely on transmissions, the Lornet 36 uses nonlinear junction detection to reveal semiconductor junctions inside electronic components. The 3.6 GHz parabolic antenna focuses transmitted energy into a narrow beam, and the receiver listens on the corresponding second and third harmonics. When the beam passes over a region containing electronics, the change in harmonic response indicates that components may be present behind the surface.
Dual-harmonic processing helps distinguish electronic responses from reflections generated by certain construction materials. Pulse mode supports broader, faster scans of surfaces, while CW mode offers more stable feedback on a specific point. At typical working distances the system can support detection of electronic components at ranges up to about 10 m, with the laser pointer used to mark the suspected location for further investigation.
Operator Controls & Workflow
The Lornet 36 allows operators to adjust power and sensitivity over a wide range so they can tune the system to the current distance and environment. Automatic channel selection across three preset bands helps find a quieter part of the spectrum, while built-in anti-jamming processing works to reduce centre-frequency interference.
During a sweep, the operator tracks changes in harmonic level on the display and listens to acoustic feedback through the wireless headset. When a significant response appears, the laser pointer is used to confirm exactly where the beam is aimed. This workflow supports a repeatable process for scanning large surfaces and then returning to specific points for closer examination with other TSCM tools if required.

Frequently Asked Question
1. What detection range can the Lornet 36 support?
In typical conditions the Lornet 36 can assist with detecting electronic components at distances of up to about 10 m. The laser pointer is used to mark the suspected location so it can be examined further if needed.
2. When should I use this model instead of a close-range NLJD?
The Lornet 36 is suited to situations where you need to inspect areas at a distance or where access is limited, such as high ceilings, structural elements or surfaces that cannot easily be reached. Close-range NLJDs remain useful when you can work directly against smaller objects or confined spaces.
3. When should I choose pulse or CW mode?
Pulse mode is generally used for broader and faster sweeps of surfaces. CW mode is used to narrow attention onto a specific point and obtain more stable acoustic and visual feedback on harmonic responses.
4. How do I handle noisy RF environments?
Use the automatic channel selection function to move to a quieter part of the band and rely on the built-in anti-jamming processing to help reduce centre-frequency interference. Power and sensitivity can also be adjusted to better match local conditions.
5. Is specialist training recommended?
As with other professional NLJDs, effective use of the Lornet 36 depends on understanding nonlinear responses and how different materials behave under inspection. Training in TSCM techniques and nonlinear detection methods is strongly recommended so teams can interpret results correctly and integrate the tool into established sweep procedures.
