Your location is close to the transmitters , the signals are VERY STRONG , NO ANTENNA AMPLIFIER is needed. A Non Amplified indoor antenna should be Ok .

Or a eve mount at the peak of the roof works well. This antenna , Winegard HD7080P is a Heavy Duty antenna so as to last a long time out side. Do Not connect a amplifier , the signals are very strong and easly overload a amplifier.
