There are three components to every commercial cellular amplifier; the donor or outside antenna, the signal booster and the internal antenna

* The donor antenna is directed towards the cell phone tower to pick up eve the faintest of signals.

* The signal booster receives the signal from the donor and then amplifies it.

* The booster then sends the amplified signal to the inside antenna which broadcasts the stronger signal throughout the building.

This process is then reversed whenever someone in the building makes a call. Watch this week’s video to learn more and visit our YouTube channel for more pro tips.
