Alternative satellite option?

we have an automatic rooftop dish (Winegard Trav’ler) which is very convenient as long as there is a clear shot of the southern sky. we selected DISH network primarily for their pay-as-you-go pricing and their ViP722k dual TV receiver/DVR. we’re very happy with our choices. i had always planned to purchase a portable automatic dish for use when we were parked with no clear view of the sky. my research turned out to be incomplete as i discovered that not all receivers are compatible with all antennas. the ViP722k is a residential model and incompatible with all portable automatic antennas. it will work with a manual antenna but i’m not interested in those...too much hassle. if/when our receiver gives up the ghost i’ll be smarter choosing a new one.
