摘要: A dielectric filter of which a characteristic is stable without a gastight casing. The dielectric filter's structure is comprised of an input, an output, a dielectric having a plurality of holes extending from a top to a bottom surface thereof, each of the holes being covered with a first conductive material, a second conductive material being electrically connected to the first conductive material at the bottom surface and unconnected to the first conductive material at the top surface, and an insulating weatherproof coating provided on the top surface.
