FactoryRegistry lists 2,990 facilities whose primary industry classification is one of the 2 industries above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced other communications systems and equipment, including telecommunications support equipment, navigational and radar antenna systems, and GPS equipment (excluding networking and audio/video production electronic equipment), in the shares shown above, and does not say which establishments. Where a plant’s own website or a federal registry names what that plant makes, it appears on the plant’s own page with the source named.
