A client in corporate security had us build these for their boardroom sweep protocol—basically popping one in a conference room before sensitive meetings to kill any rogue mics or cameras that might be tapping in. It lets you walk into a space, flip a switch, and drop a 5-30 meter bubble (roughly) where wireless signals from 135MHz all the way up to 5850MHz get swept clean. Most buyers go with the 10-unit setup for covering multiple rooms.

Each channel pushes about 1W, so total output is 10W, and you've got ten separate bands that you can toggle on or off independently—handy when you don't want to kill Wi-Fi in the next office. The 8000mAh battery gives you up to 3 hours continuous jam time, though ambient temp matters (it'll run shorter at -20°C or push closer to 3 hours in normal conditions). Dimensoins are 156×83×48mm, weight around 1.5kg, antennas included (10×2.5dB omni-directional), and it's ICNIRP compliant for safety standerd.
You'll find it useful for controlled testing environments or temporary perimeter sweeps, but it doesn't mess with wired networks or non-RF signals—so don't expect it to stop a hardline Ethernet tap. Actually, the sweep jamming is better than fixed-frequency blockers for unpredictable signal types, but teh effective range drops to 5 meters if the target signal is strong (say, a cell tower right next door). One detail you'd not think to ask: battery pack is user-replaceable, which is a pain saver after a year of regular use.

For ordering, we typically stock these, but lead time is about 20 days or so if we need to pull from factory—MOQ is 1 unit, though bulk orders drop shiping. Just confirm the frequency bands you need (we've got a 10-band default mapping) (usually 135MHz-5850MHz covered).
