Step 2  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.

Step 3  Run coaxial cable into the building to a convenient loaction (attic, etc.) where you can also get standard power for the Signal Repeater.

Step 4  Place the Signal Repeater in that location and connect the coaxial cable to the Outdoor Side of the Signal Repeater and the Outdoor antenna.

Step 5  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.

Step 6  Connect coaxial cable between the Indoor antenna and the Signal Repeater output port.
