I finally got my HR20 from CC (one of the lucky ones I guess) and my install is happening on Saturday. I know from reading that OTA hasn't been enabled yet, but my question (being new to D*) is this Do I need to have the installer put in a separate OTA antenna or does the dish cover that itself? Sorry for what is probably a no-brainer question, but I just want to make sure that I only have to have them here once and that I make sure they have everything I need when they come. TIA
