A method and apparatus for measuring resource information of a mobile communication base station antenna. The apparatus three-dimensionally measures resource information of a mobile communication base station antenna using a distance/angle measurement device, such that it can automatically measure resource information associated with azimuth angle, distance, and inclination of the antenna. The method includes the steps of: a) measuring distance and angle of a mobile communication base station antenna when an azimuth angle to magnetic north is determined, and calculating three-dimensional coordinates; b) calculating azimuth angle and inclination of the antenna based upon the three-dimensional coordinates; and c) calculating an error value of a position of the antenna based upon the calculated azimuth angle and inclination of the antenna. Therefore, the apparatus can automatically and correctly measure the resource information of the antenna, can output in real time the measured resource information, and can easily correct the antenna position based upon the real-time output information.
