B65 is an outdoor cellular frequency jammer. Not only does it block mobile phone frequencies, but it jams VHF & UHF radio frequencies, as well as WiFi 2.4GHz – 2.5GHz.
It’s easy to carry, you can take it anywhere, it goes unnoticed thanks to its color and shape, much like a suitcase. Its overall output power amounts to 128W, which allows a jamming range up to 50 – 150 meters.
As you can clearly see, it blurs low & high radio frequencies, which are 130-180MHz & 400-480MHz.
