The repeater works with two antennas (included in the kit).
One is the indoor antenna which communicates with your cell phone or laptop data card,
and another one is the outdoor antenna which communicates with the cell tower
When the indoor antenna receives the signal from your cell phone or data card,
the booster amplifies the signal and transmits it through the cable to outdoor antenna and then to the cell tower.
And the better the outside signal, the more coverage the indoor antenna can create
