The aim of this article is to the development of a novel type of parabolic antenna for cable television broadcasts. The technical quality of the broadcast was improved through the use of different spray coatings. The functional layers offer the following technical advantages: protection of the mirror surface from corrosion, reduction of the infrared radiation on the surface of the converter, absorption of the electromagnetic energy partly at the edge of antennas and reduction of their transmission to the reflector, and reduction of the impairment of the supporting structure on the antenna performance. Paper includes a German-language abstract.
