An antenna assembly generally includes an antenna module mountable to a vehicle body wall. The antenna base module may include a base, an inner (e.g., environmental protective cover, etc.) cover coupled to the base, at least one antenna element disposed within an enclosure defined by the inner cover and the base, and one or more latching members. An outer (e.g., cosmetic, styled, and/or aerodynamic, etc.) cover may include one or more snap clip members engageable with the one or more latching members when the outer cover is positioned over the inner cover. The snap clip members may include curved portions and flex points.
