Making final preps to call Directv and make the move from Dish to Directv. As I was thinking through how to make the transistion as smooth as possible (e.g. wait until the Directv install is complete and working before calling and cancelling Dish) it occurred to me that I just assume the DTV installer would just put the dish where the current DIsh dish is, since the cables are all already run for Dish and I assume he'll use those (3 TVs in very different parts of the house, upstairs and down) - but then it occurred to me that he may balk at removing the current Dish dish to put the DTV dish there. So - will the installer require someone to remove that dish before he will place the DTV dish there? (It is the best location for several reasons.) Or will he just take it off and replace it? Thanks.
