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.

ATNJ Digital 900 1800 2100 Band Selective RF Repeater with Wifi Control for Cellphone

To deal with ATNJ has been a pleasure because of the clever and special attention from Emma to assist me when our local post office neglected to make the delivery, Emma had better local information than me here in Australia. Because I live in a remote valley the local signal is very weak and the nearest tower is 20Km away. The ATNJ product has been excellent and delivers a stronger signal than two other well known products that I have tried. I am very effetively using two indoor antennas to cover down and upstairs The design is neat and effective and the instructions well describe how to instal and best practice. I can recommend this product with no hesitation.
