Installation Approaches:

1.Fix up outdoor antenna(usually use the yagi antenna) on the housetop and point to signal tower.

2.Connect  outdoor antenna to "BTS" in repeater via cable.(Notice:the machine must be away from outdoor antenna for  more than 10 meters)

3.Connect indoor antenna(usually use panel antenna)  to"Mobile" in repeater via cable(the machine must be away from indoor antenna for more than 1 meters)

4.Plug the power adaptor,power light will be lighting ,when the outdoor antenna receive the strong signal the LCD will be display the signal Please note that,when you find signal twinkling and have no full signal display  that means have no signal input and you need to check your outdoor antenna position.

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.


Working principle:

1.Outdoor antenna received the signal from signal tower.

2.Then,through cable sent the signal to the indoor repeater.

3.The repeater accepts  and improvs the signal.

4.After that,the fine signal goes into indoor antenna,via cable to  your mobile phone.
