    ADS-B signals are between 70 and 125 watts, but that is not a high power for a microwave signal which is VERY line of sight. The antennas are also mounted on the bottom of the plane, so unless your antenna has an actual view of the runway to the bottom of the plane you probably are not going to receive them once they get below roof level.
