I switched from Directv to have the international programming package Dish has. Dish network came to my house to installed the system yesterday. The installer spent 4 hours to put the superdish on the lower edge of the roof and setup 522 and 811. I paid him $20 to remove the old Directv dish. He left the base there, said it's better to leave the base there instead of patching the hole. And also he put the multiswitch at the other side of roof edge instead of puting them inside. Last night I searched this group and googled the internet. I found many people said the superdish should not be installed on the roof, and all installers were already notified by Dish network. But my installer never mentioned anything about it and just went to roof directly. He also just used the roof kits from the superdish package, didn't add any tripod as mentioned by some people. The size of the superdish is much bigger than the my previous Directv's dish. now I start to worry about my installation.
