[0003] After searching, the patent number is CN212725593U, and the name is a utility model of a base station antenna for 5G communication, including a base station antenna support rod. Through research and analysis, it is found that although the inclination angle of the base station antenna body can be adjusted during use, which is convenient for the base station to better receive and transmit signals, etc., there are still the following disadvantages to a certain extent.

[0004] For example, the base station antenna does not have a dust cleaning function. During use, the dust adhering to the surface of the antenna shell cannot be cleaned, resulting in dust adhering to the surface of the shell, which easily affects the transmission and reception of signals, thereby affecting the subsequent testing of electric buses. In order to solve the above technical problems, we have designed a ground base station with automatic dust removal for electric bus test lines. Utility Model Content
