The invention discloses a tower-shaped CPE antenna, and the antenna is characterized in that the antenna comprises a tower, a plurality of omnidirectional radiation oscillators which are installed onall surfaces of the upper side of the tower, a plurality of directional radiation oscillators which are installed on all surfaces of the lower side of the tower, and an installation flange which is installed at the bottom of the tower; the omnidirectional radiation oscillators form an upper-layer antenna, and the directional radiation oscillators form a lower-layer antenna. The structure that theradiation oscillators are placed on all faces is adopted, so the interference between radiation signals is successfully avoided, and the isolation degree is effectively improved. Meanwhile, the omnidirectional radiation oscillators and the directional radiation oscillators are arranged up and down, so that the mutual interference is further reduced, the structure is compact, the assembly is convenient, the reliability is high, the radiation performance is good, the cost is low, and the cost performance is relatively high.
