Aspects of the subject disclosure may include, for example, an antenna assembly that includes a dielectric antenna having an integrated dielectric feedline and a dielectric antenna element. The integrated dielectric feedline communicates inbound guided waves and outbound guided waves that are bound to the integrated dielectric feedline. The dielectric antenna element transmits outbound free space wireless signals in response to the outbound guided waves and generates the inbound guided waves from received inbound free space wireless signals. An actuated gimbal mount controls an orientation of the dielectric antenna element based on control signals. Other embodiments are disclosed.
