Local channels reception

Ever since directv eliminated my network package for my Rv and mandated only one recording capable receiver per house hold I have been carrying my home unit with me on trips .   I’ve been going to the same location for years and it’s apparently  slightly out of range of the local channel signal.  Formerly when I wanted to watch my local channels it would tell me that my signal strength was low and offer the option to watch in low res.  This was a fine and not much of an inconvenience.  Now in the same place it tells me that signal saver is switching to the internet.  Obviously I don’t have internet at the campground/rv so I’m out if business.  Can I turn signal saver off temporarily and go back to getting the low res option ?
