The «DEFENDER» vehicular EW system is a multi-channel modular electronic warfare station (category: Vehicular EW Jammers), designed to protect equipment and vehicles from drone threats. The basic configuration operates in 4 channels at 50 W each with the possibility of expansion to 10 channels on a single device and up to 11 channels when two devices are linked (frequency range 300–1350 MHz + 2.4 and 5.8 GHz). All elements have IP68 protection, making the system completely resistant to dust and moisture. Antennas are mounted on the car roof via powerful neodymium magnets, and control is performed from a console inside the car.

Key Features

• Name: Vehicular EW system «DEFENDER»
• Product Type: EW Jammers (vehicular version)
• Channel Power: 50 W (standard module) / 100 W (LoRa modules)
• Number of Channels (base): 4 channels with expansion capability up to 10
• Power Supply: external 12 V or 24 V (switchable by toggle)
• Cooling: passive + active (fans with IP68 protection)
• Antennas: spring omnidirectional 32×60, gain 6 dBi (included)
• Antenna Mounts: 4 neodymium magnets for car roof
• Module Protection: circulator against failure if antennas detach

Available Frequency Ranges for 50 W Modules (selectable)

• 200–300 MHz
• 300–400 MHz
• 400–500 MHz
• 500–610 MHz
• 610–720 MHz
• 720–840 MHz
• 840–950 MHz
• 950–1050 MHz
• 1050–1200 MHz
• 1200–1350 MHz
• 2.4 GHz (Mavic) — optional
• 5.2 GHz (Autel) — optional
• 5.8 GHz (video) — optional

LoRa Modules 100 W (for 3 bands from one antenna)

LoRa modules have increased noise density and cover 3 bands simultaneously from one module and one antenna. 3 configurations are available:

• 100–400 MHz (60 W): 100–200 / 200–300 / 300–400 MHz
• 420–720 MHz (100 W): 420–500 / 500–610 / 610–720 MHz
• 720–1020 MHz (100 W): 720–840 / 840–950 / 950–1020 MHz

Possible combinations of standard 50 W modules with LoRa modules: 4+1 LoRa = 7 channels, 2+2 LoRa = 8 channels, 1+3 LoRa = 10 channels. In a two-device link, an 11-channel EW system from 300 to 1350 MHz can be implemented with the addition of 2.4 and 5.8 GHz.

Advantages

• Full IP68 Protection: fans, converter, modules, relays — all components are protected from dust and water.
• Integrated Circulator: protects the module from failure if antennas detach (unlike Chinese analogs without protection).
• Powerful Spring Antennas: 32×60 at 6 dBi, do not detach under minor impacts.
• Flexible Scaling: from 4 to 10 channels on one device, up to 11 in a two-device configuration.
• Universal Power Supply: 12 V or 24 V via a switch, connects to the vehicle's electrical system.
• Convenient Control: console from inside the car — turn on/off without leaving the vehicle.
• Relay Option: optionally, relays can be added to activate specific frequencies separately (by default, all channels activate simultaneously).
• Dual Cooling: passive + active for stable operation during prolonged missions.
