KKBSTR Cell Phone Signal Booster, Home ATT T-Mobile Verizon Sprint Cellular Signal Repeater Amplifier Kit – Enhance Your 2G 3G 4G Call


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 Manual

Band: B2(1900MHz) and B5(850MHz)

Operating voltage: AC100 ~ 240V, DC5V/2A

Outdoor antenna: Lightning protection, waterproof, drain outlet down, adjustable direction, not including the mounting pole

Indoor antenna: Cable length 9.8ft, can be adsorbed on any metal, don’t get too close to the booster


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.
