Professional Grade Portable Signal Jammer - 5-20m Coverage for Conference Rooms Vehicles

One facility manager we know needed to secure their boardroom during classified discussions, and this is what they ultimately settled on after testing three other units that just didn’t hold up under real conditions—we’ve seen similar setups in high-end vehicles too, for when you need to kill any tracking mid-transit.

With 8 omnidirectional antennas feeding into sweep jamming across 2G, 3G, 4G, WiFi, Bluetooth, and GPS, the coverage radius is about 5 to 20 meters depending on how dense the signal enviornment is—that 4W total output power is enough to handle most conference rooms or a car interior without breaking a sweat.

Teh 4700mAh lithium battery runs between 2-3 hours or so when the fan kicks on during high use, which is fine for a session but means you’ll want the included car charger or AC adapter for longer deployments. It works down to -20°C, which is better than many portable units, but built-in fan is a permanent fixture—no getting around that noise if you’re in a silent room.

Basically, just order one MOQ and we ship within 10-15 days lead time unless stock fluctuates, which it does after some production cycles, so confirm before placing. The weight is 0.85kg, 132×80×41mm, and it glides into a pocket or glovebox easy. Everyone we know goes with the ICNIRP-compliant version—cheaper knockoffs don’t hold up past three months in our experience.
