I have Direct TV as well, only option for NFL. So I've researched this a bit, although I haven't done anything yet. Basically you have 2 options for Direct TV either Winegard or King. (KVH also makes satellite dishes but not portable ones.) King makes one that can be used as either a portable or roof mount and lists for $549 on their website. You can probably find it cheaper from some internet retailer. That's about $100 cheaper than the Winegard equivalent. The downside to Direct TV is you can't get HD so if you're planning to use the box from your house which is most likely HD, you can't just plug and play. At least not the last time I looked into this. There were some workarounds but I've been putting this off in the hopes that Direct TV HD will become a possibility.
