The present disclosure relates to base station antennas. One example base station antenna includes at least two antennas, at least two outer cover structures, a fastening assembly, a connection assembly, and an upper cover, and each antenna is independently packaged in a radome. The fastening assembly includes a pole and a base. A bottom of the pole is mounted on the base. The connection assembly includes an antenna connection assembly, an outer cover connection assembly, and a pole connection assembly. The pole connection assembly is disposed on the pole, a top of the antenna is connected to the pole by using the antenna connection assembly and the pole connection assembly, and a bottom of the antenna is fastened on the bottom of the pole. Each of the outer cover structures is connected to the pole by using the outer cover connection assembly and the pole connection assembly.
