Description

An RF sweep finds what is transmitting. A non-linear junction detector finds the semiconductor itself, powered or not, which is how a dormant implant is located at all.

Lornet 36 transmits between 3581.5 and 3607.5MHz through a 16 degree parabolic antenna and reads both the second harmonic at 7163 to 7215MHz and the third at 10744.5 to 10822.5MHz. Comparing the two is what separates a semiconductor junction from a corroded metal one. Pulse mode gives 18W peak for range; CW gives up to 12W for close localisation. Receiver sensitivity is at or below -110 dBm with 30 dB of dynamic range, and 22 dB of manual power adjustment.

Features

Parabolic 3.6 GHz targeting: Narrow beam helps pinpoint hidden electronics at stand-off distances.
Dual-harmonic confirmation: Second/third harmonic response increases confidence on semiconductor hits, even when devices are off.
Pulse or CW operation: High-duty pulse for wide sweeps; CW for close-in inspection and acoustic feedback.
Clean-channel tuning: Automatic frequency selection with anti-jamming algorithms reduces interference during sweeps.
Portable workflow: Telescopic rod, handheld controls, and Li-ion power support on-site inspections.

Applications

Real-World Scenarios

A Boardroom Inspection Where RF Has Come Back Clean

An implant that is switched off, or that only wakes on schedule, returns nothing to an RF receiver.

The NLJD does not care whether the device is powered. It illuminates the room and reads what comes back from the junctions inside anything electronic, which is the only way to clear a space against a dormant device.

A Wall, A Ceiling Void Or A Structural Cavity

The 16 degree parabolic beam is narrow by design, which is what makes standoff work possible.

Where a close-in probe cannot reach, the parabolic antenna lets an operator interrogate a surface from a distance and still resolve where the response is coming from. The laser targeting accessory marks the spot the beam is actually on.

A Vehicle Or Critical Infrastructure Inspection

Plant rooms, comms cabinets and vehicles are full of legitimate electronics, which is exactly why harmonic ratio matters.

Dual-harmonic analysis gives the operator the second and third harmonic response side by side. A true semiconductor junction and a corroded metal contact behave differently across those two, and reading the difference is the skill the instrument exists to support.

How it Works

Engage automatic channel search so the transmitter settles on one of the three preset bands that is quiet on site, and let the anti-jamming filter suppress centre-frequency noise.
Sweep in pulse mode at 18W peak for coverage, watching the second and third harmonic readouts rather than a single level.
Switch to CW and reduce power through the 22 dB manual range to localise. Comparing the two harmonic responses is what distinguishes a semiconductor from a false metal-to-metal response.

Frequently Asked Questions

What does dual-harmonic detection add in practice?

It reads the second and third harmonic returns together. Semiconductor junctions and corroded metal-to-metal junctions produce different ratios between the two, so comparing them is what reduces false positives on building fabric, fixings and pipework.

When do I use pulse and when CW?

Pulse, at 18W peak, is for covering ground and for standoff work. CW, at up to 12W, is for close localisation where the acoustic feedback and the finer resolution matter.

How do I handle a noisy site?

Automatic channel search picks a quiet band from the three presets and the anti-jamming filter suppresses centre-frequency noise. The 22 dB manual power range then lets you work down as you close in.

What runtime should I plan for?

At least three hours in pulse mode or two hours in CW on the 3.6V 7.8Ah Li-ion battery. The fast-charge container supports swapping between sessions.

What is the operating envelope?

Plus 5 to plus 40 degrees Celsius. Operating weight is 1.5kg, 47 by 32 by 19cm open and 32 by 32 by 22cm folded, with a packaged weight of 4.1 to 4.8kg in the transport case.

Who is this equipment for?

Technical surveillance countermeasures practitioners, corporate security teams and facilities that run their own inspection programmes. A non-linear junction detector is an operator-dependent instrument: results depend on technique, on knowing what a false response from a corroded joint looks like, and on interpreting harmonic ratios. It is not a plug-in-and-scan device.

Does it replace an RF detector?

No, they answer different questions. An RF detector finds what is transmitting now. An NLJD finds semiconductor junctions whether or not anything is powered, which is how a dormant or switched-off device is found. A full sweep uses both.
