A structural dielectrically tailored prepreg panel includes structural materials having desired electrical qualities in one or more desired areas without loss of structural integrity or the addition of parasitic weight. In one method of manufacture an applicator such as a spray nozzle applies a first dielectric material to a first area not covered by a mask. In another method, the dielectric material includes a dry material, which is sprinkled upon a tacky impregnating resin in a controlled volume percentage to provide a dielectric gradient. In yet another embodiment an applicator arrangement includes a plurality of applicators arranged to form a multiple of applicator sets which communicates with a controller to selectively activate a particular applicator and dispense a desired dielectric resin in a desired location.
