EW 8.1 Anti-UAV Systems Series 8 InterProinvest
EW 8.1 Countermeasure Systems Series 8 is a dome electronic warfare countermeasure system from InterProinvest, designed to detect unmanned aerial vehicles and create a local dome-shaped radio jamming zone. The device effectively protects perimeters, critical objects, and equipment from drones operating in various frequency bands, combining a compact dome antenna module and powerful hardware for generating radio interference.
Key Features
- Quadrafilar dome antenna for forming a directional jamming zone.
- Signal power up to 50 W per channel (also stated as 50 W per band), ensuring reliable jamming of UAV command and control links.
- Effective radio jamming range within 70–300 m, depending on configuration and environmental conditions.
- Autonomous operation from battery for up to 6.5 hours (limited by battery capacity), allowing system use in field conditions.
- Cooling system: forced-air circulation, ensuring stable operation under high loads.
- Possibility of custom manufacturing and settings to meet customer needs — changing antenna configuration, optimizing power, or integrating additional control units.

Functional Description
EW 8.1 provides targeted jamming of UAV communication and control channels in the listed frequency bands, forming a dome-shaped radio jamming zone to protect point and linear objects. Compact dimensions of 560×300×140 mm and a weight of up to 16 kg make the system relatively mobile and allow it to be placed at stationary points, temporary fortifications, or transport platforms with an existing 24 V power supply. Autonomy of up to 6.5 hours is provided by a battery — operating time varies depending on battery capacity and operating mode.
The forced-air cooling system ensures effective heat dissipation during prolonged operation at high power. Power up to 50 W per channel allows for reliable jamming in the specified sector, and the quadrafilar dome antenna forms a uniform coverage area around the device. The possibility of custom manufacturing allows EW 8.1 to be adapted to specific customer tasks — changing frequency bands, antenna configuration, power parameters, or integrating additional control and monitoring units.
The system is ideal for military units, security structures, and organizations responsible for protecting critical infrastructure, where operational and localized counter-drone measures are required. Product type: EW Jammers — Dome EW Jammers. Model name: EW 8.1 Anti-UAV Systems Series 8 InterProinvest.
