ABSTRACT:
More reliable satellite television reception in moisture conditions is provided by recognizing the critical relationship between satellite signal transmissivity and the effects of superhydrophobocity. Instead of trying to use a hydrophobic or superhydrophobic coating or material to shed water from a satellite antenna, superhydrophobic materials and coatings are strategically utilized to minimize the impact of water on the transmissivity of the satellite signal through transmissive surfaces in the antenna system. In a preferred embodiment, an exterior surface of a feed horn cover is coated with a superhydrophobic material to maintain a more consistent satellite signal reception. In an alternate embodiment, an exterior surface of a dome covering a small dish DBS satellite television antenna system is coated with a superhydrophobic material to minimize the overall satellite signal loss during moisture conditions so as to permit a dome to be effectively used over a small dish DBS satellite television antenna system.
