Airspace Protection Challenges: Refitted Drones Beat Conventional Handheld Anti-Drone Equipment

Illegal drones pose constant threats to airports, power stations, event venues and prisons. Relying on long-range low-frequency signals, modified UAVs evade outdated jammers that only block video transmission instead of core remote control links. They conduct unauthorized filming and intrude restricted airspace nonstop. Carrying multiple jammers weighs down on-site staff and slows mobile defense, while single/dual-channel devices lag far behind frequency-hopping refitted drones — a widespread headache for airspace security teams.

Equipped with 8 independent RF jamming channels, the device covers full frequency bands from 430-450MHz, 860-930MHz, 1160-1280MHz, 1360-1450MHz, 1560-1620MHz, 2380-2470MHz, 5150-5300MHz to 5725-5850MHz (Evidence: Product Specification Document). It fully matches DJI O3/O4 image transmission signals, all remote control signals of Autel series, and low-frequency control channels of modified FPV drones.

Channels deliver differentiated power output: 30W peak power for 2.4G/5.2G/5.8G bands, 20W for low-frequency remote control bands, and 10W for 1.4G/1.5G navigation bands. It suppresses three core links of drones including remote control, image transmission and satellite positioning, completely avoiding missed interception of modified illegal drones.

The overall dimension measures 396396170mm with total weight ≤6.95KG (Evidence: Product Specification Document), light enough for one person to carry by hand. A dedicated tripod comes as standard, allowing flexible switching between patrol monitoring and fixed-point protection modes. Powered by 28V DC lithium batteries, the whole machine consumes ≤300W. Directional antennas feature 1.5~3dBi gain and standing wave ratio ≤2.0, delivering stable signal output under complex outdoor electromagnetic environments for all-weather field security tasks.

The full set includes host unit, charger, tripod and bracket, with package dimensions of 425425185mm and total package weight ≤8.2KG, convenient for long-distance transportation and rapid on-site assembly. The RF module efficiency reaches ≥50%, and output power can be customized. Users can adjust specifications according to required protection distances for airports, industrial parks, border areas and other sites to meet diverse low-altitude defense demands.

Illegal drones now adopt multi-band modified signals, rendering basic high-frequency jammers useless. This 8-channel portable UAV jammer delivers full-spectrum coverage to block DJI, Autel and refitted FPV drones. Lightweight for mobile patrols and fixed-site deployment, one unit provides complete airspace electromagnetic suppression and slashes multi-device costs. It is the standard portable anti-drone solution for public security, energy sites, major events and airport airspace protection.
