KROKS RK900-50 is a low-power GSM repeater with a gain of 50 dB and an output power of 13-15 dBm (20-30 mW).

We recommend to use this model in cars and small rooms with a sufficient level of input signal, as well as an additional amplifier when connecting an external antenna to a stationary GSM-phone.

Model RK900-50 refers to the repeaters of the initial price range. Gain of 50 dB allows to improve the quality of communication only when there is good coverage at the point of installing an external antenna. This class of repeaters are used to cover small areas with a GSM signal, such as a room, a small apartment, a car.

The repeater is equipped with an indicator of power, input level and overload. The compact size of the repeater allows you to hide it in one of the compartments of the car or quietly mounted in the room.
