I am part of the channel dispute with Scripps, and looking into getting set up with OTA. Things have changed since I last had an antenna 30 years ago! I have a Hopper 3 setup, and found, but not ordered yet, an indoor digital antenna on Amazon and want to hook it through the H3 so I can record stuff. Reading through the My Dish info I see there is an adapter gizmo that goes between the H3 and the antenna ($58!), do I need it too? It's twice the cost of the antenna or is it an antenna too?
