An antenna device, provided with: a wireless device for generating radio waves for transmission or reception; a primary radiator for radiating the radio waves generated by the wireless device or feeding the reception radio waves to the wireless device; a parabolic reflector for reflecting the radio waves radiated by the primary radiator or radio waves from the outside; a shroud for shielding unnecessary radio waves from amongst radio waves radiated by the primary radiator and reflected by the parabolic reflector or radio waves radiated on the parabolic reflector from the outside; and an antenna-mounting mechanism for mounting the parabolic reflector onto an antenna attachment pole. The shroud is disposed so as to cover at least the left and right sides of the parabolic reflector, and the wireless device and the primary radiator are arranged on the inside of the shroud. The antenna-mounting mechanism mounts the parabolic reflector on the antenna attachment pole so that the antenna attachment pole is positioned at the laterally central position of the parabolic reflector. |
