An antenna assembly including a first rotating pedestal including an antenna thereon, a second pedestal supporting the first pedestal, and a dual flow rotating union having a longitudinal axis. The dual flow rotating union includes a rotating housing portion coupled to the first rotating pedestal, a stationary housing portion coupled to the second stationary pedestal, and a conduit located in the housing portion. The conduit has opposing ports oriented parallel to the longitudinal axis, a rotating section and a stationary section. One said conduit port is located on the rotating section, and the other conduit port is located on the stationary section. The housing also has opposing ports oriented parallel to the longitudinal axis. One housing port is located on the stationary portion, and the other said housing port is located on the rotating portion. |
