Jerry EW system creates directional protection against drones

The compact jammer is designed to suppress common UAVs through focused area-denial coverage

Jerry is a compact electronic warfare system designed for counter-UAV work. Its main purpose is to suppress commercial and semi-commercial drones through directional jamming rather than broad, uncontrolled radio noise.

The system is aimed at drones such as DJI Mavic, Autel and similar models, which are widely used for reconnaissance, fire correction and tactical observation. For units on the ground, this kind of threat is constant and mobile, so the response also has to be fast, portable and sector-focused.

Directional jamming

Jerry uses horn antennas and works in the 2.4 GHz, 5.2 GHz and 5.8 GHz bands. These frequencies are important for many small UAV control and data links. The stated beamwidth is 25 degrees, which means the system is designed to concentrate its effect in a selected direction.

This is different from an omnidirectional jammer. A directional system can cover a likely approach sector, a road, a defensive position or a sensitive site without creating unnecessary interference everywhere around it. In practice, that makes Jerry useful for area-denial coverage where drones are expected to appear.

Field-ready design

The system is presented as a compact and powerful EW asset with IP-65 ingress protection. That matters because front-line electronic warfare equipment is often used outdoors, moved between positions and exposed to dust, moisture and weather changes.

Jerry also has active cooling. For a compact jammer, thermal management is not a detail: sustained transmission creates heat, and overheating can reduce reliability exactly when the system is needed most.

The effective range is stated at 2,000 to 5,000 meters, depending on terrain, repeaters and weather conditions. The materials also describe field testing at distances up to 7 kilometers. In real deployment, performance will depend on placement, line of sight, the drone model and the radio environment.

Jerry fits a broader trend in modern defense technology. Counter-drone protection is no longer only about large static systems. Units need portable directional tools that can be deployed quickly, hidden, aimed at a sector and combined with detection systems, observers and other layers of air-defense protection.
