Just a word on the dish finish - Especially at those two times of the year when the satellites are close to in line with the sun (but even at other times to a degree) the dish is parabolic, meaning it will focus the sun's rays to one point. This means that all of that heat will be focused on a point.
If your dish is shiny, and a bird just happens to fly through the focal point---you guessed it
B FFFFFF T! it's fried in a millisecond.
Likewise if your face happens into that focal point. It's why you have to use flat paint. Flat paint reflects the satellite signal back just fine, but dramatically disperses the heat of the sun so as not to be deadly to living things.
On a related point, some invention and study has been done to focus the sun's rays with a parabolic reflector, so as to provide hot water to the world. The problem continues to be how to get the reflector to follow the sun without electric power and sensors.
If someone could invent a cheap mechanical clock type deal that maybe had some way to compensate for differences in dish size and weight, they would be making a real contribution to cleanliness, energy savings and the war against disease. We take hot water for granted in our world. For much of the world, all that is in warm water are crocodiles and disease.
