This DJ-087 Cell jamming device is a professional high-performance 4G Cell phone isolator, at the same time, it is also a WiFi GPS signal blocker. It has 8 high-gain antennas and 7 cooling fans, which bring us strong interference ability and quickly take away excess heat, without worrying about overheating, and easily achieve 24h/7 continuous work. The most powerful is that its jamming distance can be as high as 150M, and it can also defend against drones within a range of 500M.


1. The total output power is 170W, and you can choose 5-7dbi OMNI or high-gain flat panel directional antenna with shielding 50-150m. It still depends on the signal strength in a given area.

2. Each device can interfere with up to 6 bands at the same time, each band is independent and has adjustable power from max to off (0), LED indicators show the power.

3. 100% safe VSWR overprotection (isolator) per module.

4. Good cooling system with radiator on top and 3 big fans + 4 small internals, low noise, non-stop work
