Cellular Base Stations require efficient performance validation methods. One performance criterion is the radiation pattern. Our measurements show a radiation pattern change caused by the antenna mount structure, though industry guidance [1] does not yet control or mention this aspect of the test configuration. Consequently, the current guidance leads toward lack of repeatability. We recommend industry guidance be amended to include post-BSA distance as a test configuration parameter.
Measured Data is presented showing radiation pattern dependencies upon the mount in a CATR implementation. Explanations as to the Root Cause are stated.
