I was at a Dish retailer this morning picking up some RG-6 cable and asked him some questions. I just bought a new 1000.4 dish to use on a tri-pod camping in Florida. I asked him about aiming this dish, and he said good luck, and it might take up to 2 hours! Then he said something I never heard before, he said that these dishes come warped from the factory, and some are so bad, that the installer can't get all 3 sats. I've never had a problem with the dish 500, aiming 110, and 119 sats. What is he talking about? Is the shape of the dish as a reflector so important that you can't get a signal? Has anyone with a 1000.4 had this problem? I haven't tried this dish out yet , and won't until the middle of Dec. in Florida.
