Abstract: An antenna assembly for installation to a mobile platform includes a base portion and an antenna module capable of being removably coupled to the base portion. The base portion includes a longitudinal axis and defines a channel extending along at least part of the longitudinal axis. The antenna module includes a mount and an antenna element coupled to the mount. The mount and antenna element can be received into the channel of the base portion, in electrical contact with the base portion, and then subsequently removed from the channel of the base portion as desired. Further, the base portion of the antenna assembly is configured to accommodate multiple different antenna modules as desired.

Abstract: An antenna assembly for installation to a mobile platform generally includes a base portion and an antenna module removably coupled to the base portion. The base portion generally includes a longitudinal axis and defines a channel extending generally along at least part of the longitudinal axis. The antenna module generally includes a mount and an antenna element coupled to the mount. The mount and antenna element can be removably received, for example, slid, into the channel of the base portion, in electrical contact therewith. The antenna module may also include a cover providing the antenna assembly with a generally fin-shaped structure. And, any one of multiple different antenna modules each having, for example, different antenna elements therein may be releasably coupled to the mount as desired.
