Series 11 Starlink Satellite system. This is a great system. Just plug it in and it will search, find the satellite and self align with the satellite. We purchased new, used it twice for a total of four days. We have,in the meantime sold our Rv so have no use for it. The Series 3 model is not self articulating. Meaning you must physically find the satellite and manually point it at the satellite. They are less money but not nearly as user friendly. We paid $629.00 for this unit. Asking price $350.00. Great for camping or at the cottage. Located in Medicine Hat, Ab. For more info call or text (403) 528-9999. We will not respond to emails.
