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 !!!
