Product Description

ATNJ 1800MHz Mobile 4G Signal Repeater Booster SMA / Female for Phone 0

How It Works

Wireless network signal travels through the air in the form of waves. The outdoor antenna is designed to receive the weak signal from the air and transmit it to the indoor booster. The booster amplifies the signal based on its frequency and emits the amplified signal through the indoor antenna making it available for use.
