F27/F23/F20-5S are designed to help mobile users amplify weak signals of 2G, 3G
and 4G. They are bi-directional amplifiers.
The donor antenna receives the signals from the cell tower, amplifies it, and
transmits to the signal booster. Then the indoor antenna will receive the signal and
retransmit it to your mobile device.
The signals produced by your phone are also amplified by the indoor antenna via
the booster and donor antenna.
