ABSTRACT:
A parabolic radiation reflecting sheet member of an antenna is covered over a lower half portion of its convex side with a spaced sheet member which forms a manifold chamber with the reflecting sheet member. An upper edge of the manifold lies along a parabolic line along the midsection of the convex side of the antenna. A single hot air inlet conduit is attached to the manifold adjacent a lower edge and centrally of the antenna. A plurality of spaced hot air exhaust ports are positioned on the manifold upper edge and are each individually settable to control the flow of hot air from the inlet to the exhaust ports. The exhaust ports have a restricted aperture area to provide a pressure head in the chamber causing hot air to flow throughout the manifold chamber heating substantially all of the lower half portion of the reflecting sheet member.
