This, of course, depends on the reflectivity of the reflector. For
this reason, the reflector has a "matte" finish that will
(hopefully) scatter the long-wavelength infrared light but
accurately reflect the shorter wavelengths of the satellite signal
into the feedhorn. Flat exterior latex paint works well for this
purpose.
Actually, it's the other way around. Infrared light has a _shorter_
wavelength (750 nanometers to 100 micrometers) than satellite
television signals (1 centimeter or longer). The longer wavelength TV
signal is oblivious to the matte pattern.
