Depending on the age and model of your in-motion dish, it may not work with the format changes Dish made several years ago. If you're considering buying one of the portable self-aiming "dome" dishes, the instructions that come with them are quite good at walking you through the initial setup. After that it's just a matter of placing the dish in a location with a clear view of the sky in the direction of the satellite arc(s) your dish supports. The Winegard Pathway X2 would be my first choice since it fully supports both satellite sets for maximum aiming opportunities.
