Shtora-4 - portable radio noise generator

Shtora-4 is a jammer which provides:
  • concealment of informative emanating spurious transmissions of computers and peripheral devices;
  • suppression of receivers used for radio remote control.
Shtora-4 is a powerful wideband generator creating electromagnetic interference within the range of 0.1 to 2500 MHz with the integral output power of up to 35 W.
The generator is made in the metal body which is camouflaged in a bag.

The modification Shtora-4M provides more power for the suppression of radio microphones operating in the 400-450 MHz band.

Visual difference between unprotected and protected radio channel from information leakage. Protection is done by Portative Radio Noise Generator Shtora-4M. The measurement was done by Multi-purpose Search Device ST-031M "Piranha".
