iProtect 1240 Microwave Detector, Directional 9–44 GHz: what it is designed to do

A thorough authorised RF inspection may need to go well beyond ordinary wireless networking bands. The DigiScan Labs iProtect 1240 is built to examine activity from 9 to 44 GHz, including relevant microwave and millimetre-wave ranges.

Understanding the measurements and operating modes

The integrated directional antenna has a quoted 30-degree reception angle. Turning the detector and comparing its readings can help narrow down a possible direction of arrival. Reflections off metal and structural surfaces can distort that direction, so readings should be repeated from several positions. The claimed −40 dBm sensitivity is not a promise of any fixed detection distance.

Practical RF inspection scenarios

This is a specialist addition to a TSCM equipment set, particularly when a team wants to investigate high-frequency activity in authorised offices, meeting rooms or technical facilities. Its OLED screen displays RF Level and Modulation Level, with SILENT, ALARM and SOUND monitoring modes.

Choosing the right version

The iProtect 1240 starts at 9 GHz. It cannot check ordinary 2.4 GHz Wi-Fi, Bluetooth or other sub-9 GHz signals. The iProtect 1205 New covers 50 MHz to 15 GHz and suits a broader first pass; these two instruments overlap in part but have different antenna characteristics.

Power, handling and operational checks

The 172 × 19 mm duralumin housing uses one AA/LR06 battery. The manufacturer gives an indicative 10–20 hours of use with a reported current draw of 120–200 mA.

Strengths and limitations

This unit is not a protocol decoder or spectrum analyser. It will not detect transmitters outside 9–44 GHz or non-transmitting recorders. High-frequency RF surveys should also include a physical inspection.

Like all RF survey tools, the detector must be interpreted alongside known sources and further checks; a reading is an indication, not proof of an unauthorised device.

Comparison with alternative approaches

A directional high-frequency detector and a broadband first-pass meter answer different questions. A spectrum analyser provides more detail when signal frequency and behaviour need closer investigation. A physical search is still essential for devices that are not transmitting.

Responsible use and legal considerations

Carry out surveys only on premises or equipment you are authorised to inspect. Be aware that legitimate routers, mobile devices and communications systems will also register as RF activity.

Frequently asked questions

Does it detect standard Wi-Fi networks?

No. Its lower frequency limit is 9 GHz, above common 2.4 GHz and 5 GHz Wi-Fi bands.

Can it detect every form of 5G?

No. Only signals falling within its 9–44 GHz operating range are relevant.

Does the directional antenna pinpoint a transmitter?

It helps compare signal strength by direction, but reflections and interference can affect the result.
