Steps that describe the work of Repeater:
1) The outside antenna receives the signal from the nearest mobile base station.
2) The outside antenna sends the received signal to the installed Repeater through the coax cable.
3) The Repeater accepts the low signal and amplified it.
4) The amplified signal goes to the inside antenna through the connection coax cable.
5) The inside antenna send the amplified good signal to your mobile phone.
Choose the suitable Repeater
If your best outside signal is full bar or strongest, you can choose your suitable repeater to install your home and office. Higher output power, more coverage area. Higher outside gain, better inside signal. Less inside Antenna, stronger inside signal. If your outside signal is lower, you can choose higher gain repeater.

Steps for Installation
1. Mount the Outdoor Antenna. Choose a location for the Outdoor Antenna using your cell phone to determine the area of strongest signal. For example, on window or on roof.
2. Mount the Booster. Choose a place the Booster where you want to create a Cell Zone.
3. Use the coaxial cable to connect between the outdoor Antenna and the Booster.
4. Mount the indoor Antenna. Choose a place indoor Antenna where you need signal.
5. Use the coaxial cable to connect between the Booster and the indoor Antenna.
6. Connect the Booster to the provided power supply and plug into a power outlet.
