Advantage, simple to set up easy to use, reliable.
Disadvantage: only gets WA satellites, only works with 211 family receivers, and is finicky if you choose to use a cable longer then 50 Ft. Also, single cable connection will also prevent it from being finicky, compared to other auto dishes that do not typically have those issues.
Before people say "mine works, and it's 100' and I have it connected to 5 barrell connectors, you can even ask long controls. The manual even states no more then 50' for consistency and no splits in the cable.
I would recommend the tailgater for tailgating. It really is a great product. And really is simple to use.
