A protective coating for reflectors and a feed of a satellite terminal. The protective coating includes a multiplicity of removable sheets that can be removably attached to any of the reflective surfaces of the reflectors or to the transmitting or receiving surface of the feed, which can be referred to as the critical surfaces of the satellite terminal. The sheets can be removed one at a time when the uppermost sheet becomes dirty. Each sheet includes a substrate layer made of a suitable material such as mylar or polyester, a metallic layer on top of the substrate layer that can be, for example, specular aluminum or silver, an ultraviolet stable hydrophobic layer, such as acrylic, on top of the metallic layer, and a mild adhesive layer beneath the substrate layer allowing each sheet to be removed from the remaining sheets. The bottom sheet is attached to one or more of the critical surfaces of the satellite terminal and has a thermal coefficient of expansion substantially equal to that of the critical surface to which it is attached. The protective coating can cover either the entire reflective surface of each reflector of the satellite terminal, or only a portion of each reflective surface. Each sheet can be removed by hand without special tools.
