4. Connector Type: N Female Connector tor   packaging: 1.Signal Booster 2.English manual
3. DC 12V 2A Power Adapter   installation steps: 1. Fix the reception of the roof outdoor antenna or the high place and the turn signal point. 2. Connect the external antenna to repeater machine '' BTS '' port via cable. 3. Connect indoor antenna to repeater '' MOBILE '' port. 4. AC plug power cord into the power source and finished. 5. TIP: An outdoor antenna should be "isolated" from the internal antenna, that is, it must be constructive  obstacles (walls, partitions, etc.) between the antennas.   Note:when outdoor antenna and indoor antenna are separated not enough, then it will be self-oscillation. your  phone will not get any signal.
