I'm not familiar with Dish Traveler. But the lnb you get depends on the dish itself. A starting point would be "eastern arc" or "western arc" search but again you'll want to make sure it is compatible with the dish you have. It also depends on where you are in the country. Eastern arc is further off horizon on east coast. Same thing for Western on the West Coast... So more likely to get a better line of site. If you call or email the stores that sell them, just tell them your setup and they can likely put you in the right direction.
