- concealment of informative emanating spurious transmissions of computers and peripheral devices;
- suppression of receivers used for radio remote control.
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".
