Product Description

A digital selective band repeater is a signal booster that receives wireless signals, converts them to digital form, digitally filters out only the desired frequency bands with high precision, amplifies those selected bands, and then retransmits them. This improves coverage and signal quality while effectively rejecting interference and unwanted signals.

  • Digital - Amplifies digital signals by converting to analog and then back to digital

    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.
