 Secondly adjust the antenna directions or locations or enlarge the distance between them.
 Thirdly reduce the repeater’s gain by ATT DIP if the above methods don’t work.
The best minimum distance between donor antenna and serve antenna should be more than 10
meters.
The following measures can also be tried:
 Use the roof of the building to enlarge the isolation (Please try to place the donor antenna and
server antenna in different floors).
 Use some obstacles.(Such as wall ).
2) The repeater’s power is on but the phone is not connected into the network and still can not
communicate.
 Reason 1: There are loose or wrong connections in the repeater system.
 Solution: Please try to fasten the connections between the different parts of the system.
 Reason 2: The signals received by donor antenna of other operators nearby are too strong. (For

 Solution 1: Change the direction of donor antenna or its installation position, so that the gap of
signal strength between operators is reduced.
 Solution 2: Use barriers (like buildings) to block signals of other operators.
