EW Backpack «Cherepakha 1» — Effective Protection Against FPV Drones

Name: EW Cherepakha 1 against FPV 393-505 MHz + 508-610 MHz + 720-1025 Mhz. Brand: ZAVADA. Product type: EW Jammers > Trench EW Jammers. The «Cherepakha 1» EW backpack is designed as a portable, mobile solution for suppressing unwanted drones operating across a wide frequency spectrum. The device combines the convenience of a backpack format with high electromagnetic power to protect groups, objects, and mobile units.

Description and Purpose

The «Cherepakha 1» design is focused on rapid deployment in field conditions: its compact backpack-like body ensures convenient movement, quick connection, and operation during tactical actions. The system is developed for military and law enforcement agencies, as well as for private security units that require a compact and powerful solution for suppressing FPV drone control and video transmission channels.

Frequency Ranges

The primary target operating ranges are: 393–505 MHz, 508–610 MHz, and 720–1025 MHz. Additionally, «Cherepakha 1» provides extended coverage of approximately 290–1025 MHz and 2100–2680 MHz, making the system versatile for working with various types of UAVs and communication protocols.

Technical Specifications

• Module Power: powerful 50 W modules for each band; for the 720–1025 MHz band, increased power up to 100 W is provided, enhancing suppression effectiveness at high frequencies.
• Weight: 8 kg — lightweight for a backpack solution, ensuring operator mobility and rapid movement on the battlefield.
• Cooling: reliable passive cooling with no maintenance required, guaranteeing stable operation during missions without additional technical intervention.
• Suppression Range: from 100 m (actual range depends on environmental conditions, drone design, antenna field, and obstacles).
• Antennas: proprietary quadrifilar antennas that form a dome-shaped protection around the operator or object for effective coverage in the area of interest.
• Operating Time: up to 40 minutes on a single charge, allowing for short tactical tasks without the need for immediate battery replacement.
• Battery: replaceable 6s3p format battery for convenient logistics and quick replacement in field conditions.
• Multi-band Operation: the system supports simultaneous operation in multiple bands, ensuring synchronous suppression of FPV control and video links, increasing the likelihood of neutralizing threats.

Advantages and Features

Thanks to the combination of high output power, optimized antennas, and a well-designed energy-efficient architecture, «Cherepakha 1» demonstrates high reliability in real operating conditions. The backpack ensures rapid deployment, compact storage, and ease of maintenance. Passive cooling reduces the risk of failure due to overheating, and the replaceable battery simplifies battalion logistics and increases operational efficiency in the field.

Areas of Application

Ideal for protecting strategic objects, escorting convoys, defending command posts, and for use by mobile rapid response teams. Suitable for use in combat conditions, during training, and in civilian tasks where FPV drone suppression and prevention of unauthorized video recording or drone control are necessary.
