LKFS-J110 Fixed Pan-Tilt RF Mitigation System 9-Band 400MHz-5.9GHz airspace security 360 Degree 3km IP66 Airspace Security

The LKFS-J110 is a fixed dual-axis servo pan-tilt directional RF mitigation system engineered for all-weather, unattended low-altitude airspace security. Built on a digital-source RF hardware architecture with a high-gain directional antenna array, it transmits across 9 dedicated channels from 400MHz to 5.9GHz, covering UAV flight-control links, HD video downlinks (2.4GHz / 5.8GHz / 5.2GHz) and multi-constellation GNSS navigation signals (GPS, GLONASS, BDS, Galileo). Within its rated 0‒3km effective range in open, unobstructed line-of-sight conditions, it mitigates unauthorized UAV control, video and navigation links, so that an approaching platform loses its link and descends, holds position or returns to its launch point.

Integrated with a precision dual-axis servo positioner, the system achieves 360° continuous horizontal rotation and -10° to +60° pitch travel, with finely adjustable speeds of 0.02°‒30°/s horizontal and 0.02°‒12°/s vertical. Linked with external radar or radio spectrum sensors over an industrial RJ45 Ethernet port, it supports automated detect‒track‒mitigate closed-loop operation with a response time of 3 seconds or less. Rated IP66 and specified for -40℃ to +60℃ operating temperature, it is designed for 7*24h continuous duty at airports, energy and petrochemical sites, large venues, logistics hubs and urban low-altitude

A fixed dual-axis pan-tilt RF mitigation system that holds a 0-3km effective range over 9 dedicated channels from 400MHz to 5.9GHz, with 360 degree continuous horizontal slew and -10 to +60 degree pitch travel. Digital-source RF synthesis keeps output on frequency with no drift, and IP66 construction with -40C to +60C rating keeps the system on duty 7x24h, unattended.
