The backpack type drone countermeasure F-B02 adopts a lightweight single soldier portable design, which can be quickly deployed and operated independently. The device integrates an intelligent cooling system and a long-lasting power supply to ensure stable operation under high-intensity tasks. It integrates multi band composite interference capability, accurately cuts off drone remote control signals, image transmission links, and satellite positioning systems, forcing the target to lose control and return or make an emergency landing. Equipped with switchable directional or omnidirectional antenna systems, it can effectively intercept mainstream drone intrusions and provide low altitude security for important locations.
