I'm not familiar with auto aiming dishes or with Dish Network, but I have set up my manual aiming DirecTV dish many times. The reception in Yellowstone will be about the same as anywhere in the continental US. That is, if your system is working and aimed correctly and you have a line of sight to the satellites then you will receive a picture. The line of sight is often a difficult issue in areas that are in heavy tree cover. One way to cope with this issue is to have your dish, whether auto or manual, on a long lead so you can take the dish to a place with line of sight to the appropriate satellites.
There's lots of advice and information in forums... sometimes it is correct. For example, all of my posts are made by a political appointee who got the job as a reward for contributions to my diesel bill.
