Abstract : This patent discloses an improved rain resistance radome C-sandwich wall which is constructed of thermoplastic polycarbonate material. The cores are either posts or tubes and are bonded to the skins with polyurethane. The percentage of core material to air is adjusted by electrical tuning to make the optimum dielectric value for use in the gigahertz radar frequency range.
