A directivity dipole antenna is provided to prevent an appearance of a building or a steel tower from being damaged by being closely fixed to an exterior surface of the building or the steel tower. A directivity dipole antenna(100) includes a plurality of dipoles(120), a housing(110), a turning unit(130), and a rotating unit(140). The dipoles are vertically arranged. The housing covers the dipoles. The turning unit rotates horizontally so that the dipoles rotate in a vertical direction. The rotating unit rotates the dipoles rotatably mounted on the turning unit in the vertical direction. A turning dial(131) and a rotation dial(141) are positioned on an upper end of the housing. The turning dial controls turning angles of the dipoles. The rotation dial controls rotation angles of the dipoles. The rotating unit includes the turning dial. A support bracket(133) is fixed on a bottom surface of the turning dial to be parallel to each other.
