1. A housing for an antenna system having a plurality of antenna elements defining an antenna aperture, the housing comprising:
a chassis portion having an internal support portion for internal components for the plurality of antenna elements;
a radome portion;
a lower enclosure configured for coupling to the radome portion to define a chamber between the lower enclosure and the radome portion, wherein the chassis portion is configured for coupling to the lower enclosure to divide the chamber into an inner chassis chamber between the chassis portion and the lower enclosure and an antenna chamber between the radome portion and the chassis portion, wherein the inner chassis chamber includes a volume that is defined at least in part by the space between the chassis portion and the lower enclosure, wherein the space between the chassis portion and the lower enclosure varies across a length of the inner chassis chamber, and wherein the distance between the chassis portion and the lower enclosure varies across the length of the inner chassis chamber; and
an antenna stack assembly disposed within the antenna chamber, wherein the antenna stack assembly defines a first end that is coupled to the radome portion and a second end that is coupled to the chassis portion.
