I don't have a complete set but I have 12 panels. I got 8 of the panels replaced so far. Interesting that I lost all satellites after doing so. Elevation and declination are still correct. Couldn't find any signals by panning the dish. One would think that new panels would improve performance...... Also, I would have to remove the feed supports to replace 4 panels so I won't bother with them. Well, maybe I could take those panels out and try to reshape them.
