Manufacture of parabolic antennas

A process for manufacturing a plastic-made parabolic antenna including an electrically conductive reflector therein comprising the steps of:

• applying to a male mold, shaped to form a parabolic interior surface of said antenna, a first thermosetting gel coat;
• layering upon said first gel coat a first layer of buffer material impregnated with liquid thermosetting resin;
• layering upon said first layer of buffer material a reflective lamination layer made of a reflective net and a conductive filler of metallic bulk material comprising metal-coated chopped glass fiber material impregnated prior to layering with a liquid thermosetting resin;
• layering upon said reflective lamination layer a second layer of buffer material impregnated with liquid thermosetting resin;
• layering upon said second layer of buffer material a layer of thermosetting sheet molding material;
• covering said mold with a mating female mold having a second thermosetting gel coat applied thereto;
• and
• heating said molds under pressure to thereby harden said thermosetting materials and laminate them together.
