About KKBSTR Cell Phone Signal Booster, Home ATT T-Mobile

How a cell phone signal booster works: A cell phone signal booster uses an outdoor antenna to search for cell phone signals in the area. It captures those signals and boosts their power with a signal booster. An indoor antenna broadcasts the strengthened signal so that your phone can receive it.Package included: 1 x Host, 1 x Power Adapter(US Plug), 1 x Indoor Antenna, 1 x Outdoor Antenna, 1 x 49.2ft Coaxial Cable, 1 x User ManualBand: B2(1900MHz) and B5(850MHz)Operating voltage: AC100 ~ 240V, DC5V/2AOutdoor antenna: Lightning protection, waterproof, drain outlet down, adjustable direction, not including the mounting poleIndoor antenna: Cable length 9.8ft, can be adsorbed on any metal, don't get too close to the boosterNote:1. The indoor and outdoor antenna is best to keep the distance of more than 8m(26ft), preferably separated by walls. The outdoor antenna is preferably installed horizontally in a better signal area and toward a cell tower. If you don't know the location of the cell tower, please rotate the outdoor antenna until it gets the best signal.2. There must be 2-3 bars signals outside, otherwise the signal can not be amplified, because this is a cell phone signal repeater. A booster can only enhance the signal, can't create a signal.If you have any question, please feel free to contact us by buyer-seller messages or email, we will try our best to help you. Thanks!
