Abstract: A clamping device for securing a first component to a second component is disclosed. The clamping device includes a mounting flange coupled to the first component, a mounting seat coupled to the second component, and a clamping ring configured to be rotatably seated on the mounting flange such that the mounting flange is disposed axially between a first end of the clamping ring and the mounting seat upon assembly. The mounting seat includes a plurality of first locking ramps disposed about a circumference of the mounting seat and extending radially outward from the mounting seat. The clamping ring includes a plurality of second locking ramps disposed about an inner circumference and extending radially inward from a second end of the clamping ring. The plurality of second locking ramps is configured to engage the plurality of first locking ramps upon securing the first component to the second component.

Abstract: A tripod for a transportable SATCOM antenna includes a base with a frame centered on a center axis. A first leg is connected to the frame of the base by a first hinge, a second leg is connected to the frame of the base by a second hinge, and a third leg is connected to the frame of the base by a third hinge. A first strut extends from the first leg to the second leg, a second strut extends from the second leg to the third leg, and a third strut extends from the third leg to the first leg. The first strut, the second strut, and the third strut each include a first strut segment, a second strut segment, and a hinge connecting the first strut segment and the second strut segment. A locking collar is on the first strut segment and extends over the hinge.

Abstract: An antenna system comprises a reflector subsystem, a rotatable support structure and a support member. The reflector subsystem receives an input beam and reflects the input beam to produce an output beam steered in elevation by an elevation reflector and in azimuth by an azimuth reflector, towards a target. The rotatable support structure is operably coupled to the azimuth reflector and to the elevation reflector and is configured to rotate them simultaneously. The support member comprises a lengthwise portion coupled to the rotatable support structure and an offset portion coupled to the elevation reflector, the offset portion configured to offset the elevation reflector from the lengthwise portion. The offset portion is configured to enable clearance of the elevation reflector during beam steering of the output beam to extreme ends of a range of motion of the elevation reflector.

Abstract: Methods and apparatus for a mounting structure including a first arm having a first stiffness and a second arm having a second stiffness, wherein the first stiffness is less than the second stiffness in at least one degree of freedom. The first arm includes a flex region that can deflect in response to loading. In embodiments, the mounting structure can movably secure an antenna array to a pedestal.

Abstract: A coupling is provided that includes a shaft, a hub, a retainer and a fastener. The shaft includes a plurality of shaft splines. The shaft splines are arranged circumferentially about an exterior of the shaft. The hub includes a plurality of hub splines, a hub bore and a hub fastener aperture. The hub splines are arranged circumferentially about the hub bore. The hub splines are mated with the shaft splines. The shaft is within the hub bore. The retainer includes a plurality of retainer splines, a retainer bore and a retainer fastener aperture. The retainer splines are arranged circumferentially about the retainer bore. A first of the retainer splines circumferentially overlaps and is axially next to a first of the shaft splines. The shaft is within the retainer bore. The fastener is within the hub fastener aperture and the retainer fastener aperture. The fastener connects the retainer to the hub.
