Full description
Twelve bands for mobile and radio networks
The handheld 12 frequency all in one MJ-12A12W jammer for GSM, 3G, 4G, 5G, WiFi (b, g, 11.a), GPS, LoJack, VHF, UHF networks allows you to adjust the output power and manage the activation for each single frequency channel for the selective signal jamming of cell phones or wireless devices, making the latter absolutely unusable.

Equipped with removable omnidirectional antennas, it can cover distances up to 20 meters (depending on the signal strength).
