I found that dish will screw giant lag bolts right through the shingles of your roof, right next to 3 other abandoned dishes. They are no longer allowed in our complex. I finally identified all the abandoned ones (alost all of them now as they are phased out), removed them and patched all the shingles. Filled an entire dump trailer. It was ridiculous. Had to repair ceilings from the leaks. Cable company is almost as bad. They leave all the old wires up, run new ones right over top. Putting nails through all the siding. But at least they aren't destroying the roof.
