ARA Anti-Drone Jammers EW3 Series
EW 3LF
EW for countering FPV UAVs operating in the 700-1050 MHz frequency band.
Functions
The EW 3LF electronic warfare (EW) system is designed to counter FPV drones operating within the 700-1050 MHz frequency range. It features three separate jamming bands, utilizes Collinear antennas (or optionally Dome antennas), and can generate interference across all bands simultaneously – effectively disrupting communication with the most common FPV transmitters.
EW 3LF is a reliable and efficient solution for UAV defense. Thanks to its technical characteristics and operational advantages, it becomes an indispensable tool for ensuring the security of military installations, critical infrastructure, and personnel.
The system saturates the airwaves with interference, making it impossible for drone pilots to maintain flight. It is capable of jamming attack FPV drones at distances ranging from 70 m to 400 m. The device is powered by either 220V AC or 28V DC.
One of its key advantages is its lightweight design – only 6 kg, with compact dimensions of 350×230×140 mm, making it easy to transport and store.
The unit also boasts a wide operating temperature range from –30°C to +50°C. The enclosure is made from heat-dissipating materials and includes a cooling system to prevent overheating. With an IP54 protection rating, the system is resistant to dust and water ingress.
EW 3MV
For countering Mavic quadcopters. Has three separate jamming bands 2360-2500 MHz, 5150-5300 MHz, 5725-5850 MHz.
Functions
EW 3MV is an EW tool for countering Mavic quadcopters and others operating in the 2.4 GHz, 5.2 GHz, 5.8 GHz frequency band, has three separate interference bands and has the ability to jam in all bands simultaneously. EW 3MV has three separate interference bands 2360-2500 MHz, 5150-5300 MHz, 5725-5850 MHz, and has the ability to jam in all bands at the same time.
EW 3MV is a reliable and effective solution for protection against drones of the DJI Mavic series and others and will provide protection against resets. Due to its characteristics and advantages, the EW 3MV will become an indispensable tool for ensuring the security of military facilities, infrastructure and people.
Thanks to the dimensions of 350x230x140 mm and a weight of 6 kg, the EW 3MV electronic device has become even more versatile, its body is made of heat-dissipating materials that help to avoid overheating, thereby ensuring its proper productive operation. EW 3MV anti-tank missile system is ideal for the protection of troops, infrastructure, and civilian objects located both on land and at sea. The EW 3MV works at frequencies of 2.4 GHz, 5.2 GHz, 5.8 GHz, has 3 antennas that amplify and pick up communication.
The model also received a wide operating temperature from -30°C to +50°C. The level of moisture protection and protection against dirt IP54 will not let dust and moisture inside the case.
Thanks to its characteristics and advantages, the EW 3MV will become an indispensable tool for ensuring the safety of military facilities, infrastructure and people from Mavic quadcopters and other drones.
