The SDi antenna is VERY old and it could easily be an end of life event. You only have a few months left before the antenna is not able to receive the full DTV line up but the good news is that what ever line-up you can receive will be in HD. Yep, DTV and HD with a dome! Coming in early 2020.
Forget about post about the battery. That's not the problem.
Does that receiver work at home or is it an RV receiver only? Certainly possible the receiver died but also possible the antenna/LNB died. Do you / can you connect the receiver to a standard home antenna?
