Installation Overview

1. Select a location with the strongest signal on the roof of the

building to install the Outdoor Antenna. Make sure the antenna

is pointed directly at the desired cellular tower and there are no

obstructions that could block the signal. You should also

consider attaching a grounded lightning protector between the

outdoor antenna and the Signal booster.

Select a location to install the Signal Booster that is in a

secure indoor location near a grounded AC power source and

well ventilated away from excessive heat, moisture, and direct

sunlight.

Select a location(s) for the Indoor Antenna(s), being sure to

take isolation distance requirements into account. In general,

long narrow spaces will benefit most from directional panel

antennas while more square spaces will benefit more from

omnidirectional dome antennas.

Proper antenna distance is essential to prevent signal

oscillation (feedback) that can interfere with the cellular tower

and as a precaution the amplifier will shut off in the affected

band. Distance is measured in a straight line from the outdoor

antenna to the closest indoor antenna. The closest allowable

distance depends on several factors such as booster gain

level, cable and splitter loss and building wall materials.

Typical minimum distances are shown below:
