I am considering switching from dish but am concerned about line of site. Right now I am on an eastern arc set up with dish hitting the 72 and 61.5 signals. I have no line of site for 119, 110, or 129 due to trees. My dish setup is on a pole between 125-150 feet from my house just to clear the trees . What satellites will I be hitting to get HD programing on Direct. My zip code is 27302.
