Abstract:
1. A microwave antenna that includes: A) a base; B) a primary reflector that forms a central opening, is pivotably mounted on the base, and is so shaped as to define a reflector axis such that the primary reflector directs microwaves received from parallel to the axis to a focal region located on the reflector axis in front of the primary reflector; C) a sub-reflector so shaped and positioned in the focal region as to reflect microwaves that the primary reflector has directed to the focal region; D) a low-noise block down-converter of which at least most is disposed behind the primary reflector; E) a feed tube that forms a feed-tube mouth and is so shaped and positioned as to direct through the central opening and into the low-noise block converter microwaves reflected by the sub-reflector after having been directed to the focal region by the primary reflector; F) a set of at least one first fastener that secures the primary reflector to the low-noise block down-converter or the feed tube without securing the primary reflector to the other of the low-noise block down-converter and the feed tube; and G) a set of at least one second fastener, separate from every said first fastener, that secures the feed tube to the low-noise block converter; wherein each said first fastener secures the primary reflector to the low-noise block down-converter without securing the primary reflector to the feed tube.
