An antenna apparatus is provided with an antenna cover formed so as to widen toward the rear and to rise in a streamlined shape toward the rear along the longitudinal central axis, an antenna base to which the antenna cover is attached in a watertight fashion, and an antenna section accommodated in a space formed by the antenna cover and the antenna base. The antenna section is set upright on the antenna base, and has a configuration in which an antenna wire of predetermined length corresponding to a frequency band of medium frequency wave to very high frequency wave is wound vertically at a predetermined inter-wire pitch around a winding member accommodated in a space corresponding to the raised section of the antenna cover. |
