Functions
The device “Grets 3M” is an EW tool designed to counter FPV drones operating in the 700-1050 MHz frequency range. It features three separate jamming bands, using either dome antennas, and can simultaneously jam all bands, blocking communication with the most popular FPV transmitters.
The EW “Grets 3M” is a reliable and effective solution for protection against drones. Due to its features and advantages, it becomes an indispensable tool for ensuring the safety of military facilities, infrastructure, and people.
The EW “Grets 3M” fills the airwaves with interference, preventing pilots from continuing their flight. The device is capable of jamming strike FPV drones at distances ranging from 70 m to 400 m. It can be powered by either 220V or 28V.
A key advantage of the model is its weight of 6 kg and compact body dimensions of 304x184x77 mm, making it easy to transport and store.
The model also operates within a wide temperature range from -30°C to +50°C. The housing is made from heat-dissipating materials and includes a cooling system to prevent overheating. The IP 54 protection rating keeps dust and moisture from entering the device.
Thanks to its features and advantages, the EW “Grets 3M” becomes an indispensable tool for ensuring the safety of military facilities, infrastructure, and people.

HOW DIFFERENT TYPES OF ANTENNAS WORK
Collinear antennas – on a moving object (Fig. A). The drone enters the effective range of the electronic warfare device while it is moving, unable to fly over the moving unit. They provide a greater range of interference propagation.
Dome-type antennas – on stationary positions (Fig. B). They provide better coverage over the protected object but have a shorter range.
PRODUCT DESCRIPTION:
Power supply:
The device operates on 220V and optionally on 28V, with separate inputs for both.
220V connection – IEC 60320 / C7 (figure eight), cable included.
28V connection – TX60 (yellow) – optional. Consultation required when ordering.
Controls:
The controls are buttons on the body for power and enabling each interference band separately or all at once.
- “Power” button – turns the power on/off.
- Lower position – turns the device on. If the “Power” button indicator is lit, the device is powered and ready for use.
- Upper position – turns the device off, indicator not lit.
- “1” button – turns the first interference band (700-820 MHz) on/off.
- Lower position – turns the band on. If the “1” button indicator is lit, the band is active.
- Upper position – turns the band off, indicator not lit.
- “2” button – turns the second interference band (800-920 MHz) on/off.
- Lower position – turns the band on. If the “2” button indicator is lit, the band is active.
- Upper position – turns the band off, indicator not lit.
- “3” button – turns the third interference band (900-1050 MHz) on/off.
- Lower position – turns the band on. If the “3” button indicator is lit, the band is active.
- Upper position – turns the band off, indicator not lit.
In standard models, button presses are accompanied by light indicators, but this may not be present in some versions.
