The LKST-UJ920H+ is a portable, handheld RF signaldetection and management device engineered for low-altitude airspace monitoring applications. Designed forsingle-operator use, it combines passive spectrumsensing, UAV signal identification, and directional RF
output into a compact, lightweight form factor suitablefor field deployment.The device achieves 360° omnidirectional spectrummonitoring with second-level detection response. Uponidentifying a target UAV signal, the operator canimmediately activate the directional module to executefocused signal management within a 30° emission cone at
distances up to 2 km.Suitable for: airspace compliance monitoring, eventperimeter management, critical facility RF security, andauthorized low-altitude safety applications.
