Why are the big commercial satellite dishes always white? Thermal noise!
And I never understood why C band back yard consumer dishes were black. They could have gotten a few more DB of C/N if painted white.I used to work in that industry on the uplink side.
P.S. With DBS dishes, DirecTV, Dishnet, it's not significant.
