I am new to this forum and new to Directtv. I have my home recently set-up with a H25 with a directtv recorder (can't remember the number). I also have an H25-500 unit that I want to put in my second home. At this point I don't have a clue as to what dish or other equipment I need for my second setup. When the installer set my home up he also configured my H25-500 unit. Please help me figure out what dish I can use, I saw on craigslist quite a few directtv dishes for sale, will they work for me? I will probably have to reconfigure the H25-500 for the new equipment. How do I do that? Thanks Jim
