Manufacturer / Brand (from product data): Asgard Defence Technologies. Category: EW Jammers (in product structure: EW Jammers > Trench EW Jammers). Product ID: 4749. The device is designed for rapid deployment on vehicles, positions, and for personal protection of personnel.
Description and Purpose
The Miniature EW Jammer "Hela-2A" is a versatile anti-Mavic system, designed as a lightweight and mobile means of protection against Mavic family drones and against munition drops. The body is made in the form of a compact box with dimensions of 210mm*100mm*150mm (technical specifications also list dimensions as 210mm x 150mm x 100mm) and a weight of only 2.5 kg (body + antennas). The device is conveniently installed on a vehicle roof using magnets, mounted on positions, or carried on an infantry backpack.
Operational Capabilities
The system blocks drone control channels in two operating bands: 2400-2500 MHz and 5725-5850 MHz. It provides an effective jamming range of up to 300 m, provided the distance between the drone and the drone operator is up to 3000 m. The device is equipped with a remote control for convenient operation from a distance.
Power and Autonomy
The EW jammer can be powered by DC sources 12V, 24V, 28V or from a 220V mains supply via a 220→28V power supply unit with a recommended current of at least 10 A. The autonomous operating time from the system's battery is up to 4 hours, allowing tasks to be performed in field conditions without frequent recharging.
