RDN-420B radio jamming equipment mainly completes directional and full-band electronic jamming of aerial targets (model aircraft, drones, etc.), receives real-time azimuth information from radar, radio detection, and photoelectric equipment, controls the turntable to achieve all-round 0°~360° coverage, and effectively interferes with drone remote control, image transmission, and satellite navigation signals to make them return, force landing, and drive away.
