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 Booster, 1 x Power Adapter(US Plug), 1 x Indoor Antenna, 1 x Outdoor Antenna, 1 x 15m(49.2ft) Coaxial Cable, 1 x User ManualFrequency: 850MHz(B5) and 1900MHz(B2)Operating voltage: AC100 ~ 240V, DC5V/2AOutdoor antenna: Lightning protection, waterproof, drain outlet down, adjustable direction, not including the mounting poleIndoor antenna: Cable length 3m(9.8ft), magnetic base, can be adsorbed on any metalApplications: Can be used for apartment, hotel, office, basement of buildings, coffee shop and shopping mall etc.Note: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 faces the nearest cell tower.2. Need 2 to 3 bars signal outside, otherwise the signal can not be amplified, because this is a cell phone signal repeater.If you have any question, please feel free to contact us by buyer-seller messages or email.
