      cell phone signal repeater  photo :                  Why we should buy cell phone repeater/ signal booster/ GSM amplifier :   Cell phone becomes especially helpful when people get into critical situations. In case of emergency a timely call can save somebody's life. Unfortunately, there are still some places where one can find themselves "out of coverage". Usually those places are either too far from the cell phone base station or located inside underground constructions, for example: · Parking lots, tunnels · Big stores, office buildings · Cars, boats etc. · House in remote areas   How is  mobile phone signal repeater GSM/DCS/ 2G/3G/4G WORKING ?       •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.   A regular cell phone amplifier consists of: · 1 - Outdoor antenna like YAGI antenna (including 10 meters standard cable) (you also can     buy from us) · 2 - Indoor omni antenna (you also can buy from us) · 3 - 5 meters standard cable · 4 - Power supply (DC 10v) · 5 - User's manual · 6 - Cell phone amplifier    Features of mobile phone signal booster  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 repeater Installation diagram (very convenient and easy to install)       Company Information             Our Services            FAQ   After- Sales Service   We have 12 months quality guarantee for all customers, you can return goods to us when receive defective repeater, but air freight charges should be responsible by buyer.     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.
