ABSTRACT:
A grid-type microwave antenna, easy to manufacture, assemble and disassemble, is formed of a number of spaced reflector rods which, when mounted in a frame, form a parabolic reflecting surface. The frame includes U-shaped channels for mounting and supporting the spaced reflector rods. Each of the rods has a curvature so that the combination of the rods spanning the frame forms a parabolic reflector. The frame is formed by channels having holes to receive the central and the end portions of the reflector rods. Insulating sleeves are provided for the central portion of each rod. Insulating cups are used for the end portions of each rod.
