Abstract: An antenna is provided that includes a mast, a first dipole, and a second dipole. The first dipole crosses with the second dipole, and the first dipole and the second dipole form a first antenna assembly that is coupled to the mast. A hybrid power divider is coupled to the first antenna assembly, and an internal feed system, positioned within the mast, is coupled to the hybrid power divider. The antenna may include a rigid coaxial internal and external feed system.

Abstract: A separator jet to separate a first liquid from a second liquid upon which the first liquid is floating. The separator jet has a main body with a base and a top. There is an inlet nozzle in the base to receive a transport fluid. An outlet nozzle with a diameter larger than the inlet nozzle receives fluid from the inlet nozzle and is positioned within the main body to define an inlet for the first and second liquids in the top of the main body. An inlet in the base of the outlet nozzle, adjacent the inlet nozzle, receives the first and second liquids and allows the first and second liquids to be transported by the transport fluid out of the outlet nozzle. The jet may be mounted on a float and, in the preferred embodiment, may be mounted on a vessel that can be anchored in a waterway to clear oil from that waterway or mounted to be able to sail in polluted water.
