    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.
