Abstract

The present invention relates to an electric downtilt angle adjustment apparatus and a base station antenna. The apparatus comprises a position selection transmission assembly and a phase shift assembly. The position selection transmission assembly comprises a support frame, a moving switching mechanism, a transmission gear, and a second guide shaft. The second guide shaft is mounted on the support frame, and multiple transmission intermediate wheels are mounted on the second guide shaft at intervals, the transmission gear being configured to drive the transmission intermediate wheels to rotate. The moving switching mechanism is mounted on the support frame. A driving member is disposed on the moving switching mechanism. The phase shift assembly comprises multiple driven members. The apparatus has the advantages of having a simple structure, being convenient to manufacture, low in cost, and light weight, having a small size, and having reliable quality.
