I just got an HDTV-integrated TV, and am now considering getting the Dish Network.  I have a regular antenna hooked right now, and it works fine.  I even get some local channels in HDTV, and they look great.  If I get regular Dish Network (without DishHD), will I still be able to get my local channels in HDTV like I am now, or will it make it worse by making all of my channels analog?  If it's the second one, can I use my antenna for local channels and then my dish for the other channels?  I don't care whether I get the non-local channels in HD.  Thank you so much.
