How is the GSM/3G signal repeater works?

Step1 Start by taking your phone up to the roof or other location outside to find where the signal is strongest.

Step2 Temporarily mount the Outdoor (outside) antenna in that location. You may need to adjust and move the antenna later. More notes on Donor antennas here.

Step3 Run coaxial cable into the building to a convenient loaction (attic, etc.) where you can also get standard power for the Signal Repeater.

Step4 Place the Signal Repeater in that location and connect the coaxial cable to the Outdoor Side of the Signal Repeater and the Outdoor antenna.

Step5 Mount your Indoor (inside) antenna in a productive location. You may need to adjust or move the antenna later. More notes on Indoor antennas and patterns here.

Step6 Connect coaxial cable between the Indoor antenna and the Signal Repeater output port.

Step7 Power up the system and check for signal inside the building. If needed, tune system by moving and or pointing the Outdoor and Indoor antennas until they get the most signal possible.

Step8 Secure all antennas and cables, securely mount the Signal repeater and clean up the installation.
