I just moved and the new house doesn't have an outdoor attenna. I will be living in town and don't want to pay for hd locals (which I don't think they offer yet in my market) when I can get them from free. I'll be replacing one vip 722 and one 510 for two 612. So I will have one vip722 and two 612. Can I just go to the store and buy just any attenna and hook it up to all the dish boxes? Right now I can get local channels using a coat hanger hooked up to a converter box so I'm thinking that I don't need something too expensive. I just don't want to have to install an anntenna on the roof and run wires to every dish box if all I can do is by three cheap $15 ones from the store and hook it up them too the back of each dish box.
