Abstract: A subarray of a planar array antenna has a ground plane having a rear face and a front face, radiating elements, each of the radiating elements protruding forward of the front face and physically mounted to the ground plane; circuit elements electrically coupled to the radiating elements, and physically mounted to the ground plane and positioned rearward of the rear face of the ground plane; and a dielectric radome supported on the ground plane defining a continuous surface sealed to the ground plane. The continuous surface includes a forward wall positioned forward of each of the radiating elements to form an environmental seal around the radiating elements. The radome has an intermediate wall intermediate at least one pair of adjacent ones of the antenna elements.

Abstract: A bird feeder has a vertical feed container with a top, an open bottom, and a continuous sidewall. A feed tray is positioned below the open bottom in spaced relation thereto and extends outwardly from the sidewall. The feed tray has an open top and an open perimeter edge. A perch is mounted on the tray and is located below the upper perimeter edge. A transparent hood element is mounted on and extends around the feed container. It has a lower edge which is positioned below the upper perimeter edge of the tray and above the perch. This permits the perch to dwell below the hood in the clear visibility of the birds which will attract the birds to fly within the hood, locate themselves on the perch, and feed themselves from the tray. The perch has a diameter less than the lower diameter of the hood to provide a space between the outer perimeter of the perch and the outer perimeter of the lower edge of the hood for the birds to move through to land on the perch.

Abstract: The lawn border and edging member of this invention has an elongated vertical wall member which has opposite vertical side surfaces, first and second opposite ends, and elongated top and bottom surfaces. A flat plate member is secured to the bottom surface of the wall member and has a width extending outwardly from each side of the wall member to maintain the wall member in a vertical position. The outer ends of the plate member extend longitudinally outwardly beyond each end of the wall member. The plate member has an offset portion on its bottom surface to receive an end extension portion of another juxtapositioned member having an end extension portion and an elongated horizontal slot to receive an end extension portion of another juxtapositioned member having an end extension portion. The wall member has connecting means on its opposite ends for pivotal attachment to the ends of similar wall members.
