Mobile jammer are becoming more and more important to protect mobile security or police forces while operating in a high-risk environment. Due to this reason unival has developed the PWJ1, a portable, fully digital wideband jammer.

The PWJ1 enhances the jamming capabilities of any moving squad significantly, but can be also used to establish a secure zone in the field.

Components and the software of the PWJ1 are specified according to the customer’s requirements, thus achieving best possible jamming results.

The unival PWJ1 presents the latest generation of highly portable, intelligent & digital wideband jammer. Using state-of-the-art software along with the best hardware components available, the PWJ1 achieves an unrivaled jamming performance.
  • 100 % German technologies: all main components and system parts are made in Germany, full system certification in TECCENTER, Germany
  • FPGA/ 6 DDS control board for real-time programming of system
  • Communication window can be programmed
  • Multi-operation modes: Barrage, Sweep, Multi-Sweep, hopping with database
