  1. Product Overview<\/strong><\/li>\n<\/ol>\n

    The SS-HJ300 Portable Counter-UAS Handheld Detection & Jamming Device is a highly integrated low-altitude defense product developed by Salem Science Limited. It combines passive RF detection and multi-band electromagnetic jamming in a single rifle-style unit, providing a complete single-soldier counter-UAS solution.<\/p>\n

    The device detects illegal drones via radio-frequency scanning, feature recognition and decoding, capturing control and video-transmission signals in real time with 360\u00b0 omni-directional coverage. Once a target is identified, it rapidly initiates electromagnetic suppression to sever the drone\u2019s remote-control link, video link and navigation signal, forcing the UAV to return home or perform an emergency landing.<\/p>\n

    Featuring an ergonomic rifle-style design with balanced weight distribution and a low centre of gravity, the SS-HJ300 weighs only 4.0 kg (basic version) and supports tool-free hot-swap batteries, making it ideal for extended mobile patrols, major-event security and critical-infrastructure protection.<\/p>\n
