A stackable antenna enclosure is generally dome-shaped with a top and a side wall tapering inward from its base. An antenna and associated electronic components are mounted on the interior top surface of the enclosure. A series of enclosures can be stacked together for storage or shipment, but the side wall of the enclosure includes a number of stops that limit how far the enclosure can be inserted into the interior cavity of an adjacent enclosure to prevent the antenna and related electronic components from coming into contact with the top of the adjacent enclosure. For example, the stops can be a series of vertical ribs extending radially outward from the side wall of the enclosure. The upper ends of these ribs will abut the base of an adjacent enclosure when stacked and prevent contact against the antenna and related electronic components.
