EW System "Pysets" 290-390 50W + QUADRIFILAR Antenna 350MHz

We offer a ready-to-use electronic warfare (EW) system "Pysets" manufactured by ZAVADA. This is a mobile solution for the rapid suppression of UAV communication channels and remote control units at short and medium distances. The system combines high-power nodes, a modular design, and a proprietary 350MHz quadrifilar antenna system, ensuring stable operation in field conditions.

Briefly about its purpose

The system is designed to protect objects and territories from drones through effective radio suppression in the 290–390 MHz range. Thanks to 50W power per band and a well-designed antenna scheme, reliable signal jamming is ensured while maintaining simple operation and rapid deployment.

Key features

• Range: 290–390 MHz;
• Transmitter power: 50 W per module;
• Suppression radius: up to 200 m with a distance to the drone operator of 3.9 km;
• Antenna: proprietary 350MHz quadrifilar, providing dome coverage and increased stability of the jamming signal;
• Modularity: replacement of individual modules or addition of new ones for system scaling;
• Cooling: reliable passive cooling for fault-free long-term operation.

Package contents

The standard kit includes everything necessary for quick deployment and operation:

• EW "Pysets" (290-390 50W);
• Quadrifilar antenna 350MHz;
• 2220 Wh battery (optional);
• Remote buttons — 2 pcs.;
• Remote controls — 2 pcs.;

Warranty and operation

Warranty period: 6 months. The warranty does not cover mechanical damage or powering on the device without a connected antenna. It is recommended to follow the manufacturer's instructions and use the recommended configuration to maintain warranty obligations.

Additional options and accessories

Additional accessories and services are available to expand functionality, allowing the system to be integrated into various platforms and power sources:

• Adapters and extensions for antenna and power (antenna extensions, power adapters for other batteries, car terminal adapters);
• Car mount and car charger, fast charger;
• Adapter for external battery with terminals;
• Uninterruptible power supply unit from ECOFLOW.

Thanks to its modular design and powerful 50-watt transmitters, the "Pysets" system from ZAVADA is an effective tool for the rapid suppression of UAV communication channels and remote controls in situations where reliability, deployment speed, and ease of maintenance are important. The 350MHz quadrifilar antenna provides stable coverage of the aiming angle and high stability of the suppressed signal, while passive cooling increases reliability during long-term operation.

The product belongs to the EW systems category (specifically, Trench EW systems) and is released under the ZAVADA brand. If individual solutions or additional adapters for integration with power sources are needed, our team will manufacture the necessary adapters to order. Technical questions and customization options are discussed with specialists before purchase — contact us for consultation and selection of the optimal configuration according to your tasks.
