I have considered replacing it with an HD antenna but now that I have punched a hole in it from one of those height restriction I-beams (that's a fun story) I need to either do that or another device...
We had in motion Sat years ago and on the east coast, where we camp with tree cover etc, we found it to be more of a hassle than it was worth. With cellular data coverage in pretty much most areas of the country, streaming is easier and cheaper. A hotspot, an unlimited data plan and a firestick, you can get whatever you want without any additional equipment on the roof or the ground. And MUCH cheaper than a dome/dish and Sat plan through dish or DTV.
