AT&T Cell Phone Booster Installation guide

Installation Tips

1. Before installation:

Please make sure that the frequency band of your phone matches with that of the

cell phone booster. For details of the testing methods, please refer to the User

Shopping Guide

If the testing result does not match, the booster can't work for you, but we can

replace a correct booster for you, please don't worry and contact us. If you are not

sure, you can also contact us.

2. Tips for installation:

(1) Find a place with the strongest signal on your roof to install outdoor directional

antenna as high as possible, keep it aimed at the near tower of your carrier.

(For iPhone ios system, you can download "Cell Towers US" app; For Android, you

can download "lte discovery" or "open signal" app to check the location of the

signal tower.)

(2) The indoor panel antenna should be mounted on the center of a wall,

about 5-6ft high.

(3) The outdoor and indoor antennas should be separated by a wall and kept at

least 25ft distance, facing away from each other.

Note: Do NOT Power On the Booster if Both Antennas are Not Connected !!!
