#Separate indoor antenna and outdoor antenna by walls.

[ 1 ] Mount the External Antenna where you have the strongest cell phone signal, typically on a roof or in an attic.

[ 2 ] Connect the indoor antenna to the Repeater Base Unit and place where you need improved signal. There should be a minimum of 2 vertical meters of separation between the Base Unit and External Antenna.

[ 3 ] Run the RG-6 coax cable (10 meter) between the Base Unit and External Antenna.

[ 4 ] Connect the power supply to the Repeater Base Unit and plug into a power outlet and you are done!

When outdoor antenna and indoor antenna are separated not enough, then it will be self-oscillation. Your phone will not get any signal.
