The outside antenna catches the low signal from the mobile base station and delivers it to the cell phone
amplifier through the connection cable (coax).
After the signal is accepted by the phone amplifier, the device amplifies it.
Then this amplified signal goes through the connection cable (coax) to the inside antenna.
And after that, the amplified signal transmits to the cell phone.
Features of mobile phone signal amplifier
A. High-gain linear power amplifier
B . ALC and AGC function technology ,
C. Ultra-low noise receive amplifier
D. There is no interference to the base station ,right after the opening of the original system and the base station without the need to adjust parameters ,
E. Stable and reliable electromagnetic compatibility design .
F. The base station dose not cause an increase in background noise ,but will not lead to a decline in the quality of the base station communications
G. With full-duplex communication mode .
H. dispel the heat effective reasonable ,the structure is pretty ,the volume is suitable .
Signal problem & installation technique supporting
1.If still weak signal receipt after installation, please check if outdoor antenna point to signal tower correctly or elsewhere has stronger signal and confirm signal strength achieve-70DBM.
2.If still have no signal after installation, please check our device power adapter whether connected perfectly? And connectors connect well.
3. If strength is not steady, please check if outdoor and indoor antenna is too close; please ensure outdoor antenna has distance of 10 meters at least, with a barrier and not in a same horizontal line.
4. Packed the outdoor connector by waterproof glue, otherwise wet reduce the signal cover area.
