How should you install repeater (very easy and simple):


  • Step 1: Use your mobile phone to test signal strength outside house or on roof, -70dbm is the basic requirement (full bar).
  • Step 2 Install outdoor antenna in that location and keep adjusting, point it to signal tower station, try to get best signal.
  • Step3: Run outdoor coaxial cable into building in a convenient location to connect with signal repeater.
  • Step 4: Mount your indoor antenna with signal repeater
  • Step 5: Power up signal repeater device to check the signal inside, moving outdoor antenna until you get satisfied signal.


Note: Connect outdoor (BTS) port with outdoor antenna, connect indoor ANT(MS) port with indoor antenna, outdoor antenna is mounted at a higher position. Both antennas should be 10 meters far away from each other at least. Indoor and outdoor antenna must be separated by wall.
