-If you still don't know how is the important to the outdoor antenna,I advise you read carefully.
-Outdoor signal is received by the outdoor donor antennas and through the signal booster enhance the signal strength.Finally indoor antennas "put" the signal to the place where you want to enhance the mobile phone signal strength.
-All right,the whole process of signal enhancing is like that.But please catch a important point,if outdoor antennas can't receive the signal well,any outpower signal booster can't enhance the signal anymore.I think most of people feel that as long as the signal booster is strong enough,so they can enchance the weak signal normally.In fact,it's wrong,signal booster can't enchance signal when absolutely no signal.
-When your home or someplace haven't any signal bar,please find a higher place where can receive one or two signal bar,and then install a high gain outdoor antennas,that's the right way.
-Sometimes you see the outdoor antennas they mark as 9/13dBi,but actually they only 2dBi or 3dBi.They can't receive signal well,so the signal booster can't work perfectly.
-Callboost must be your the best choice,you must choose a professional and honest supplier.
