Repeater GSM900 (EGSM) and UMTS900 signals 900 MHz 70 dB KROKS RK900-70M

KROKS RK900-60 is a GSM900(EGSM) and UMTS900 signal repeater with a gain of 70 dB and a maximum output power of 20 dBm (100 mW).

We recommend to use this model in cars and small rooms up to 200 sq.m. with a sufficient level of input signal.

Model RK900-70 refers to the repeaters of the initial price range. The gain of 70 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 GSM signal, such as a room, a small apartment, a car.

The repeater is equipped with a detailed indication that allows you to diagnose the presence of a ring and overload.

The repeater has an automatic gain control system, and for more fine-tuning, there is a manual adjustment in increments of 2 dB (up to 30 dB).

Basic properties repeater RK900-70M:

• extended EGSM range;
