I. Main Product Positioning
The 8-band drone signal jammer with replaceable batteries (hereinafter referred to as the "jammer") is a portable countermeasure device designed specifically for dynamic airspace management. With full-bandwidth signal jamming and a modular power supply design, it enables rapid interception, suppression, and control of small and medium-sized civilian drones. It is widely used in various scenarios, such as public safety and critical infrastructure protection, and represents a new generation of airspace defense tools that combine professionalism and practicality.
II. Key Advantages
1. 8-band full coverage, no blind spots during jamming
The device integrates eight main frequency bands: 430-440 MHz, 900-930 MHz, 1.2 GHz, 1.4 GHz, 1.5 GHz, 2.4 GHz, 5.2 GHz, and 5.8 GHz. It precisely covers the drone's flight control communications (main 2.4 GHz/5.8 GHz bands), satellite positioning (GPS/QZSS/GLONASS/Galileo), and data transmission channels. The power of a single channel can reach 10-40 W, and the total RF power exceeds 170 W.
Flight control jamming: The maximum jamming range for drones in the 2.4 GHz band reaches 2,190 m (at a drone altitude of 500 m), and for the 5.8 GHz band, it is 2,590 m;
Position jamming: The GPS signal jamming range remains stable within 750-770 m at a drone altitude of 50-200 m, completely disrupting navigation communications.
2. Replaceable battery, continuous operation
Uses a high-capacity rechargeable lithium-ion battery, supports hot swapping, and is equipped with a dedicated battery monitoring system – real-time voltage, charge, and temperature monitoring, with configurable high/low voltage and temperature alarm thresholds, and an automatic audible alarm in case of malfunction.
A single battery provides 1-2 hours of continuous operation, and with a backup battery, it can operate 24/7.
Supports a slow charging mode to ensure stability and battery life when fully charged.
3. Portable design and intelligent controls for enhanced combat effectiveness
Ergonomic design: High-strength PC+ABS housing weighs only 4 kg, is easily held with one hand, and is suitable for long solo battles.
Precision Guidance System: Equipped with a 10x magnification sight and a 25° conical directional antenna, it forms an 80-meter-diameter beam at a range of 200 meters, ensuring visual tracking with sufficient accuracy.
Multi-Mode Control: Supports independent activation of one frequency band, allowing selection of modes such as "Return to Base," "Departure," and "Forced Landing," with a response time of ≤4 seconds.
4. Adaptability to Harsh Environments, Maximum Reliability
Using the VCO RF architecture and MMIC integrated circuit technology, the device has been tested in high and low temperatures, operating stably in the range of -20°C to 55°C. High-density SMT mounting significantly improves vibration resistance, making it suitable for challenging scenarios such as field conditions, high-altitude areas, and coastal zones.
III. Typical Application Scenarios
**Critical Facility Protection:** In scenarios such as substations, oil storage facilities, and power lines, the device can reduce unauthorized drone intrusion incidents by 80%, minimizing safety risks such as short circuits.
**Public Security:** At large events, VIP security, and border control, the device can quickly intercept unauthorized drone flights, preventing aerial imagery theft or deliberate damage.
**Emergency Response Scenarios:** During disaster relief and counter-terrorism operations, the device can disable image transmission and drone control within 5 seconds, ensuring the safety of the work area.
IV. Product Compliance and Quality Assurance
**Complies with national radio regulations.** Its directional radiation design prevents interference with surrounding civilian communications (false interference rate less than 0.5%). The device has passed the tests of the Ministry of Public Security and has become the preferred choice for procurement by public security systems in various regions.
