VPJ-2
VPJ-2 vehicle protection jammer
A vehicle-mounted jamming unit for protection against radio-controlled improvised explosive devices and unauthorised use of cellular communication devices, blocking up to three frequency bands between 100 and 800 MHz simultaneously and independently within a 5-10 metre radius of the vehicle.
