ABSTRACT:
A dish antenna structure (10) is formed from a plurality of ribs (14) which extend from near the center of the dish to its periphery, and which support antenna panels (18) between them. Each rib has an outer flexible plastic sheath having grooves (44,45) in its side edges which receive the edges of antenna panels (18) and a hollow longitudinal channel (40) within which a rigid support member (42) is fixed. The support ribs (14) and the antenna panels (18) are curved such that the anterior surface of the dish defined thereby is parabolic.
