I am having SBC install a E* system on the 24th (1-811, 1-522) replacing my single SD receiver D*system and wanted to make sure that they are installing the correct dish so that I do not have to have it done again in the near future - with the (hopeful) addition of more HD's, I'd rather them install what I'll need for tomorrow as well as today... I am guessing that they will want to swap dishes, rather than install the E* dish separately? Hopefully I'll be able to get onto the roof to intall my OTA (CM4228, CM7777, CM9521A) before they arrive so I can tie it all in together at once. Any advice?
