An antenna assembly is provided that includes an antenna element depending from an antenna mounting base. The mounting base includes a shaft portion that uniformly tapers from a mounting end portion to a projecting end portion. The shaft portion includes grooves, or flutes, that each extends from the mounting end portion toward the projecting end portion, and that each has a curvature about an axis of the shaft portion. The grooves provide the shaft portion with an asymmetrical cross-sectional area that causes airflow impinging on the shaft portion to generate turbulence and scatter low air pressure regions that tend to form locally around the shaft portion. As a result, small vibrations generated by the low pressure regions are suppressed, and whistling sounds, noises, etc. associated with the vibrations may be reduced.
