Provided is a detailed configuration regarding a method of transmitting a driving force etc., of an antenna adjustable of an elevation-depression angle and an antenna circumferential angle. A weather radar antenna may include an antenna unit, a column, an elevation-depression-direction drive transmission shaft, and a circumferential-direction drive transmission shaft. The antenna unit may receive at least an electromagnetic wave. The column may support the antenna unit. The elevation-depression-direction drive transmission shaft may transmit a driving force of an elevation-depression-direction drive motor to the antenna. The circumferential-direction drive transmission shaft may transmit a driving force of a circumferential-direction drive motor to the antenna unit.
