A. Change the installation position and direction of theoutdoor antenna.

B. Change the direction of the outdoor antenna to theamplifier signal transmission line (choose the straightest and nearestroute, do not turn too much).

C. Make sure that the distance between the outdoorantenna and the indoor antenna is too close (too close to form aself-excitation), and that if the distance is more than 20 meters, it must beseparated by walls and concrete floors to prevent the signal emitted by theindoor amplifier from being received by the outdoor antenna causingself-excitation.
