A backpack that carries 400 watts of jamming power is the newest answer to a problem that has grown fast on the battlefield: small FPV drones that are cheap, numerous and hard to stop with a fixed system. The Geran-8, made by Shenzhen Nuoxinyuan Tech, is an eight-channel, man-portable drone jammer built for a single operator to carry, switch on and walk with.
Eight channels, 400 watts
The Geran-8 puts out 400 watts in total, split across eight channels at 50 watts each, all jamming at the same time. Its bands cover the links FPV drones depend on: the 400 to 1,000 MHz range in six slices for control signals, plus 2,400 to 2,500 MHz and 5,725 to 5,950 MHz for video and data links. Working together, the eight channels form a jamming field with an effective radius of 300 to 500 metres, depending on the environment.
That combination is what makes the unit practical. A single-band jammer can be sidestepped by a drone that switches frequency; a multi-channel system that covers control and video bands at once leaves the aircraft with nowhere to go.
Built to be carried
The whole unit weighs about 15 kilograms including its battery, carried in a rugged backpack frame. Eight omnidirectional antennas mount on the frame and must be extended vertically for the best coverage. A rechargeable lithium battery pack runs the system for 45 to 90 minutes of continuous operation, depending on how many channels are active and on conditions in the field.
The Geran-8 is built for outdoor use in any weather, with an operating temperature range of minus 20 to plus 55 degrees Celsius. It is rain-resistant for field operations, though it should not be submerged in water. Setting it up takes seconds: put the backpack on, secure the shoulder straps and waist belt, extend all eight antennas and switch the unit on. The jamming field switches on automatically once the system is running.
There is one warning the maker stresses. Never run the device without all eight antennas properly connected, or the radio-frequency modules can burn out. Keep it away from water and extreme heat while it is operating.
Who it is for
The Geran-8 is aimed at single operators, special forces and mobile security teams. Its listed uses run from personal protection and VIP security to border patrols, counter-smuggling work, mobile checkpoint security, hostage rescue and counter-surveillance. In each case the job is the same: one person, on foot, carrying their own drone defence with them.
Delivery takes 3 to 10 working days, and the unit carries a 12-month warranty. The maker, Shenzhen Nuoxinyuan Tech, is based in Longgang District, Shenzhen, and describes itself as a factory specialising in counter-drone equipment.

Why it matters
Backpack jammers fill the gap between handheld devices and fixed-site systems. They need no infrastructure, no vehicle and no setup time beyond putting them on, which makes them the fastest counter-drone option to deploy when a threat appears. As FPV drones spread from the battlefield to borders, checkpoints and VIP protection, demand for man-portable jamming keeps growing — and the trade-off is always the same: power and battery life against weight a single person can carry. Backpack jammers in this class match RF Apex’s JB-8B and JB-12B backpack jammers, and the Geran-8 shows where the category is settling: eight channels, around 400 watts, and roughly 15 kilograms on the back.
