PROBLEM TO BE SOLVED: To make adjustment of an antenna direction easy in consideration of, for example, the amount of rainfall attenuation depending on the distance to a communication opponent in the wireless apparatus for treating a received signal by the antenna. SOLUTION: The level of a signal received by an antenna 2 is detected through a receive level detecting means when the signal is transmitted by radio from the communication opponent. The distance to the communication opponent is detected through a distance detecting means.On the basis of the detected results of the receive level and the distance, the determination about received level is performed through the receive level determining means. A determination result information generating means 12 generates the information about the determined result. COPYRIGHT: (C)2004,JPO
