Well, the satellite dishes in my area are mostly grey, not white - but to the question - why painted and not mirrored?. The wavelengths that need reflecting by the parabolic mirror of the satellite dish are in the microwave range - a millimetre or so.
So, the dish need only be smooth compared to that length, and a paint finish meets that standard, though of course, most of the reflection is done by the metal of the dish. The paint need not be radio-conductive or radio-reflective.
Were the dish needed to operate in the optical range, then indeed, a mirror finish would be needed.

Why do people have satellite dishes?
People have satellite dishes to receive television signals from satellites orbiting the Earth. These signals provide access to a wide range of TV channels and programs. Satellite dishes are often used in areas where traditional cable or internet-based TV services are not readily available.
What satellite dishes beam radio waves to satellites above the Earth?
Satellite dishes that beam radio waves to satellites above the Earth are typically referred to as ground stations or satellite uplink dishes. These dishes are designed to transmit signals to satellites in geostationary or low Earth orbits, enabling communication for television broadcasting, internet services, and other data transmission. They usually have a parabolic shape to focus the radio waves into a narrow beam directed towards the satellite.
Are satellite dishes tacky?
The answer is YES, they look horribly taky (unless they are well mixed with surrounds, which is hard to find).
Why are satellite TV dishes in the northern hemisphere pointed south and in the Southern Hemisphere pointed North?
Satellite TV dishes in the Northern Hemisphere are typically pointed south because the satellites that provide the TV signals are positioned over the equator. In the Southern Hemisphere, the dishes are pointed north for the same reason, as the satellites are still positioned over the equator but appear to be in the northern part of the sky from that perspective.
Why do satellite dishes face south?
Most communication satellites orbit at or near the equator. In the northern hemisphere this is obviously to the south. In the southern hemisphere it is to the north, so the dishes would point north.
Why are satellite dishes painted gray?
I believe that grey and white reflect radio waves and black absorbs it. That is why large radio telescopes have either white or gray dishes.
When was Down in the Shacks Where the Satellite Dishes Grow created?
Down in the Shacks Where the Satellite Dishes Grow was created in 1992.
Are there any satellite dishes on mercury?
No.
What is the average size of a satellite dish?
The average size of a satellite dish is from 1.5 to 2 yards. Residential satellite dishes are usually smaller, while satellite dishes for commercial use tend to be larger.
Why must satellite dishes face a certain direction?
DISH Network satellite dishes must face a certain direction in order to allow the dish to correctly align with the necessary satellite orbitals.
What is a difference between a dog's ear and a satellite dish?
satellite dishes are not composed of flesh
Are there different shapes and sizes of satellite dishes and which is the best?
Yes, there are different shapes and sizes of satellite dishes. You can find the best one for your home at www.montanasatellite.com/satellite_dish_covers.htm
How big are satellite dishes?
very.....big..:P
What satellite company used big satellite dishes?
If you are referring to the original satellite dish known as the C band satellite, the satellite company that used these was DISH Network.
Does anyone still use the big satellite dishes?
Yes, there are people that still use the big satellite dishes. You can even buy them at www.ringolake.com/sat_dish/sat_main.html or www.skyvision.com/
What is TVRO?
TVRO (Television Receive-Only) refers to satellite dishes used for receiving satellite television signals. These dishes are typically larger than DBS (Direct Broadcast Satellite) dishes and are commonly used for receiving programming from satellites located in geostationary orbit. TVRO systems were popular before the advent of smaller DBS dishes.
