Abstract
Shroud isolation, including choke shroud isolation, apparatuses for wireless antennas for point-to-point or point-to-multipoint transmission/communication of high bandwidth signals, and integrated reflectors including a shroud or choke shroud. A choke shroud systems may include a cylindrical body with an isolation choke boundary at the distal opening to attenuate electromagnetic signals to, from, or within the antenna. The isolation choke boundary region may have ridges that may be tuned to a band of interest. The isolation choke boundary may provide RF isolation when used near other antennas.

A parabolic antenna reflector apparatus, the apparatus comprising:
- a parabolic reflector section having a central axis of symmetry and a circular opening perpendicular to the central axis of symmetry;
- a shroud portion extending distally from the circular opening, the shroud portion having a distal opening;
- a radome covering the distal opening;
- an integrated radio transceiver and feed comprising an elongate housing enclosing a substrate, transceiver circuitry on the substrate, an antenna radiator extending from the substrate;
- a central opening through the parabolic reflector section through which the integrated radio transceiver and feed passes;
- and
- a holder mounted on a proximal side of the central opening so the central opening is continuous with an inner chamber within the holder, wherein the inner chamber secures the integrated radio transceiver and feed so that the integrated radio transceiver and feed is aligned with the central axis of symmetry.
