Stay Connected ... Wirelessly!
The DA4000SBR requires no physical connection to your phone. How does this work? An outside antenna receives the signal from the cell tower, the signal is amplified by the DA4000SBR unit and repeated to your cell phone through the inside antenna. No physical connection to your phone means you now have the freedom to walk around while talking on your phone. This technology even allows clean and clear wireless functioning of multiple cell phones operating on 800 and 1900MHz bands simultaneously, with a coverage area up to 5,000 square feet.¹

¹Coverage area is based upon an outside signal strength of -70dB. As outside signal strength decreases, coverage area decreases. For poor outside signal areas or for increased interior coverage, use a yagi (directional) antenna.
