Find your outside signal strength
Use the signal bar indicator on your cellular device to determine the approximate outside signal strength as per the chart below.
Note: Even if your device shows no bars or “no service” it is possible that there is enough cellular signal for the booster to achieve
communication with the network.
Installation and Setup
• Mount the outside antenna on the side of building or roof where the strongest signal is indicated on your cellular device.
• If mounting the antenna outside is not possible place it on a window where the strongest signal is indicated on your cellular device.
• Inside and outside antennas require as much distance (separation) between them as possible to avoid feedback loop (oscillation).
When feedback occurs the booster automatically lowers its gain which reduces coverage area. If this occurs you should turn
off the unit and try to relocate the antennas to be further apart.
• Flashing green LED lights indicate gain reduction. If the green lights on the booster are flashing, please refer to the user manual
for detailed instructions on how to interpret the flashes.
• Perform a test installation with the booster kit before drilling any holes in walls to ensure that you have the correct booster kit
model which achieves the desired coverage area.
