I have dish and receive my local channels in sd. I have the top 250 package with 211k reciever and 222 reciever. I have been a customer for over 15 years and have always bought my own equipment as well as install. I also use a reciever in my RV setting it up with a portable dish. I live in central Arkansas at least 75 miles from where my local stations are broadcast. I am using a,dish 1000 at my home currently. What do I need equipment wise to get my local channels in HD?
