Suggest you locate a local Dish tech (not Dish itself) and have them look it over. For around $200 service charge you can know what exactly you have...or you can start all over with a Dish Traveler SK-1000/Hopper 3 and associated controls for around $2k. And, yes, if you like to park in tree-covered areas, a hard-mount on the roof can be useless. And the portable ones work well also.
