All, I am going to use Dish Network at my tailgate for the first time this year and have a question. I have a Dish 500 setup on a tripod connected to a Dish 211. I was able to use a compass and get 110 and 119 with a strong signal. My question is how do I find 129. I am really interested in having HD so I figure I need to re-point to 119 and 129. What is the best way to find this. My zip code is 72704. Thanks
