The JDY-200 Handheld Drone Jammer is a professional-grade countermeasure device designed for emergency response and critical location protection, quickly establishing a safe "buffer zone" in complex electromagnetic environments. Supporting simultaneous multi-drone jamming and full-band coverage, the device suppresses the remote control and image transmission links of mainstream commercially available drones, forcing them to hover, return, or make an emergency landing. This effectively ensures low-altitude safety and order in densely populated and sensitive areas.

• Multi-Drone Concurrent Interception: Optimized power amplifier and waveform scheduling algorithms enable simultaneous suppression of multiple targets in scenarios such as group and accompanying flight, reducing airspace response time.
• Full-Band Compatibility: Broadband coverage for major brands and their commonly used frequency bands, compatible with both new and existing models and multiple standard protocols, enabling universal countermeasures with "one device, multiple models" control.
• Security in Crowded Scenarios: Controlled, targeted energy projection reduces electromagnetic interference from unrelated areas, improving mission controllability and safety in densely populated areas such as large-scale events, shopping districts, schools, and areas surrounding train stations/airports.
• Weight-Balanced Ergonomic Design: The body's counterweight is meticulously calibrated, aligning the center of gravity with the natural wrist angle. The anti-slip grip and shoulder attachment significantly reduce arm fatigue from prolonged use.

• Urban patrols
• Security for major events
• Establishment of temporary no-fly zones
• Perimeter protection for key infrastructure
• Accompanying law enforcement evidence collection

Overall, this device is designed with "wide coverage, robust adaptability, ease of operation, and minimal burden" in mind, providing users with rapid, reliable, and sustainable response capabilities against rapidly evolving low-altitude threats.
