APX-JB-8B Backpack Anti-Drone Jammer

The APX-JB-8B is a backpack anti-drone jammer for dismounted patrols, convoys and temporary checkpoints. Its 8 jamming bands cover the drone control and video links and reach up to 2 km, while the man-portable pack keeps the operator mobile.

It delivers 300–500 W of jamming power from a soft backpack housing, with a high-capacity battery for extended field use. The directional and omnidirectional antenna options let the operator focus the jamming on a single threat or screen a wide area.

With a 3-second response time and a 16–20 kg carry weight, the APX-JB-8B gives patrol teams a powerful counter-drone capability without a fixed installation or a vehicle.

Eight Antennas in a Camo Pack

The camouflage pack carries eight tall antennas — one for each jamming band — seated in pouches across the back of the unit, so the full 8-band set travels with the operator.

The camo housing keeps the pack discreet on patrol, and the backpack format gives the mobility and concealment a vehicle or fixed system cannot match.

Worn on the Move, Controlled by Remote

Worn on the back, the pack leaves the operator's hands free — a wired remote switches the jamming bands on and off without taking the pack off.

One-touch activation and fast frequency switching give a 3-second response, so the operator can answer a drone threat the moment it appears.

Directional Panel in Hand

The flat directional panel antenna puts the jamming power where the operator points it, focusing the 300–500 W on a single threat.

Directional and omnidirectional antenna options let the operator focus on one drone or screen a wide area, depending on the mission.

Application Scenarios

1) Dismounted Patrols & Border Security

Carried by patrol teams on foot, the APX-JB-8B jams hostile drones at up to 2 km, protecting border posts, patrol routes and forward positions with no fixed installation.

2) Convoys & Mobile Protection

For convoy escorts and mobile security details, the backpack jammer moves with the team and screens the column against drone surveillance and attack.

3) Temporary Checkpoints

At temporary checkpoints and roadblocks, the APX-JB-8B sets up in seconds and denies drone coverage over the checkpoint area, forcing intruding drones to land or return.

4) Public Events & VIP Protection

Suitable for public events, outdoor gatherings and VIP protection details. The man-portable pack deploys wherever the threat appears, without waiting for a vehicle or fixed system.
