Abstract: An antenna system for a wireless network that provides multi-band and/or multi-sector operation from a single location is provided. The antenna system may provide improved control and adjustment of antennas contained within a compact design to allow sectors of coverage provided by the antennas to be modified to accommodate different cell site parameters that may otherwise have been satisfied using a more distributed arrangement of antennas.

Abstract: The invention is directed to methods and systems for adjusting the vertical beam width of an imbalanced antenna. In one embodiment, first and second antenna arrays are imbalanced because one of the arrays has at least one more radiating element than the other. The additional gain created by additional radiating element(s) distorts the beam and alters the coverage area of the corresponding array, in embodiments. The tilt of the array having at least one more additional radiating element(s) is modified using phase shifting technology and based on the tilt of the array having fewer elements. By modifying tilt of the array having at least one more additional radiating element(s), the upper 3 dB points of the first and second array may be aligned to correct for the distorted beam and altered coverage area between the first and second arrays.

Abstract: A transportation tool for transporting a single composite aircraft fuselage section, including a first spindle weldment mounted on a first structural tower, and a second spindle weldment mounted on a second structural tower and configured to couple the single composite aircraft fuselage section to the structural towers. A first gimbal assembly configured to allow the first spindle weldment to move independent of the first structural tower, and a second gimbal assembly configured to allow the second spindle weldment to move independent of the second structural tower.

Abstract: A rotating internal support for a large hollow structure can include a rigid central truss and two or more annular disks coupled to the truss by support arms. The annular disks can be axially spaced along the longitudinal centerline of the truss, and can be coupled to the support arms by guide rollers that allow the annular disks to rotate about a central axis. The internal support can also include support rods with contact pads that extend axially around the annular disks to contact and support the inner surface of the large hollow structure.
