An antenna device includes: a radio device generates radio wave for transmission or radio wave for reception; a primary radiator that radiates radio waves generated by the radio device or feeds received radio waves to the radio device; a parabolic reflector that reflects the radio waves radiated from the primary radiator or radio waves from an outside; a shroud that shields against unnecessary radio waves among the radio waves radiated from the primary radiator and reflected by the parabolic reflector or the radio waves radiated to the parabolic reflector from the outside; and an antenna mounting mechanism that fits the parabolic reflector to an antenna attachment pole. The shroud is arranged so as to cover at least a right and left of the parabolic reflector, the radio device and the primary radiator are arranged inside the shroud, and the antenna mounting mechanism fits the parabolic reflector to the antenna attachment pole so that the antenna attachment pole is located at a lateral center position of the parabolic reflector. |
