  • Patent number: 8760361
    Abstract: A polarization adjustment assembly for a reflector antenna is provided with a radio bracket with a mounting flange. The mounting flange is coupled to a hub provided with a stop portion. Fasteners couple the radio bracket to the hub via slots in the mounting flange, rotatable with respect to the hub within the extents of the slots. An adjustment bolt passes through a boss coupled to the mounting flange. The adjustment bolt abuts the stop portion, whereby longitudinal displacement of the adjustment bolt with respect to the boss rotates the radio bracket with respect to the hub. Alternatively, the positions of the boss and stop portion on the mounting flange and hub may be exchanged.

  • Patent number: 8698683
    Abstract: A dual polarized reflector antenna assembly, provided with a reflector dish coupled to a feed hub with a feed port there through; a transceiver support bracket coupled to a backside of the feed hub; a circular to square waveguide transition coupled to the feed port; a square waveguide coupled to the circular to square waveguide transition; an OMT coupled to the square waveguide; the OMT provided with an OMT intersection between a square waveguide and a pair of rectangular waveguides oriented at ninety degrees to one another, an output port of each rectangular waveguide arranged normal to a longitudinal axis of the dual polarized reflector antenna assembly. Alternatively, a circular waveguide may be applied between the feed port and the circular to square waveguide transition, eliminating the square waveguide, or the rectangular waveguides may be extended longitudinally, also eliminating the square waveguide.

  • Patent number: 7898497
    Abstract: A reflector antenna mount for a reflector antenna with a primary mount coupled to a support arm. The primary mount rotatable in a first axis relative to the support arm. A secondary mount coupled to the primary mount; the secondary mount pivotable in a second axis relative to the primary mount. The reflector antenna coupled to a front side of the secondary mount; an electronics enclosure of the reflector antenna positioned on a back side of the secondary mount, the electronics enclosure coupled to the reflector antenna. A dielectric enclosure provided with a front face and a side surface coupled to the primary mount. The front face spaced away from the reflector antenna, outside of a range of motion of the directional antenna in the second axis.

  • Patent number: 7802370
    Abstract: An antenna feed angular alignment tool for an antenna feed and method of use. The tool having a body with a bore between a first end and a second end; a capsule, retained within the bore, having a first material and a second material enclosed within a cavity of the capsule. Coupling feature(s) integral with the body, proximate the first end are configured to rotationally couple with the antenna feed. The first material and the second material having different densities are movable within the capsule, indicating when the capsule and thereby the tool are aligned with a horizontal plane.
