Normal problems :

when LCD display full signal and no signal amplified , there are 2 possible reasons :
1. Imput signal is too good ( up to -45dbm ) ,it cause big interference ;

solution : try to test outdoor signal strengthness to see how much dbm can display on phone ( android or ISO phone is ok to test ) .Then move outdoor antenna to a place where is -50dbm around or -55dbm ( it is best condition ), or move antenna not face to a base station, or adjust it to lower gain or change a smaller power booster .

2. auto oscillation ,reason is that unreasonable cable and antenna installation ,they are too close . it cause big positive and negative feedback together .
solution : dont put indoor and outdoor antenna in same direction , separate them by walls .

3. Weak signal received and display 1-2 bars , means outdoor signal is weak too ;
solution : go to a place where is enough good signal , change outdoor antenna to a higher gain one .
