Patent Images
1. An antenna dish, such as may be used for reflecting and focusing electromagnetic signals such as television signals transmitted from satellites for reception and use, comprisingcentrally disposed supporting means for supporting the components of the dish;
- a plurality of elongated forming ribs, each comprising a tubular member that is bent prior to assembly of said dish to form a portion of generally parabolic curve, each said tubular rib having formed integrally therewith mesh receiving portions comprising at least one recess extending inwardly of said tubular member and generally parallel to said parabolic surface thereof for receiving a portion of metallic mesh therewithin, each said rib being attached at one end thereof to said centrally disposed supporting means and extending generally radially outwardly therefrom;
a plurality of foraminous metallic mesh members each formed of a mesh material reflective of said signal and extending between a pair of adjacent said forming ribs and received within said mesh receiving portions thereof and each extending radially outwardly continuously from a position adjacent said centrally disposed supporting means to a position adjacent the end of said ribs distal said supporting means; and
rim means connected to the end of said forming rib distal said supporting means, whereby the mesh members and ribs extending continuously outwardly from the centrally disposed supporting means form a generally parabolic dish structure for reflecting and focusing such signals.
