TIP: An outdoor antenna should be “isolated” from the internal antenna, that is, there must be constructive obstacles (walls, partitions, etc.) between the antennas.
When the distance between the external antenna and internal antenna is not far enough, both antennas will receive signal from the other one, then your phone will not receive any signal.
A mobile phone signal repeater provides the ultimate solution in any area where
Cellular communications can not work well due to leak of signals,the repeater
Device features easy installation & operation ,build-in indoor antenna and no
Interferece,it could also improve indoor electromagnetism environments.
Protract cellular battery life and reduce radiation of cellphones.
A mobile phone repeater is ideal for house ,home,office use.
High gain ,easy installation and operation.
Full-duplex,singal-port design,build-in power supply.
Use ALC technology ,adjust extent automatically.
LED light working &signal condition indicators.
Big linear power,control intermodulation & scatteration stably.
Problems and solutions ( important ) , please read :
All booster will be tested before shipping to ensure quality , if you dont know any about booster and installation please start from 0 as below .
