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.
