The small-sized lock of cellular communication of Shtil-K of the increased power with an expanded range of suppression.

Product Shtil-K order

Please complete all required fields.


The product is intended for blocking of cellular communication of the GSM 900/1800 and 3G standards, 4G, LTE, Wimax on the average action radius (to 80 meters, but in each case the distance of blocking depends on remoteness of the device from a base station) in conditions when its use has to be hidden from external supervision.

Use options

The product can be applied to local suppression of cellular communication in borders of small perimeters.

Execution options

The lock is executed in the compact plastic ergonomic case, has no external antennas and other unmasking signs. Takes place on a wall, at the height not less than 1 meter from a floor.


    Provides effective blocking of operation of devices of cellular communication on the average action radius, due to application of the special patented types of modulation of the interfering signal, optimized under concrete standards of communication.

    Has no unmasking elements that allows to hide its use from external supervision.

    Has smooth adjustment of power of each channel of suppression, up to shutdown that allows to use the lock in different rooms and to adjust it under specific conditions

    Doesn't demand additional control before operation.
