RDN-428 High-power full-band jamming system is designed and used for countering the threats of UAV. It mainly completes the full-band (10MHz~6GHz) interference of aerial targets (airplane model, UAV, etc.), making the airplane model and UAV lose data links control and satellite navigation signals. It uses the full-frequency jamming system to suppress the radio signals of the enemy in a wide frequency band and at a long distance, so that various aircraft will lose control and ensure the air defense tasks of key directions, important areas and key targets.
