Rain film or oil contamination on the radomes can cause a decrease of antenna efficiency. A newly developed hydrophobic and oleophobic easy-to-clean coatings caneffectively reduce the adhesion time and adhesion of rain and grease on the surface of radomes， resulting in a self-cleaning effect.Three different types of coatings systems were selected，and the hydrophobic and oleophobic performance evaluation，high frequency transmittance test andverification of weatherability and environmental adaptability were carried out.The results showedthat the selected nano-coatings system provided excellent comprehensive performance inhydrophobicity and oleophobicity，high-frequency wave permeability and weather resistance，and was suitable to be used for radomes that required hydrophobic and oil-repellent performance.
