GSM repeater Signal GSM-80A A6740 amplifies the signal inside the building. It is an ideal device for use where there is insufficient signal for your mobile phone and is suitable for various buildings and spaces where gsm signal coverage is difficult (underground and reinforced concrete structures, bars, games rooms, etc.) Which are shaded by sheeting or wide walls.
The device is no longer on sale because of its unreliability. We service the device permanently from the competition.
