I had questions concerning Direc Tv standard broadcast also. Spoke with a Direc Tv specialist this morning 4/5/2019. Actually someone here in the USA.They actually called me. Told him I had a winegard in motion unit and was using a h20 receiver. I wanted to know what was happening with the standard def signals. His reply was. If you have a high def receiver you will still have tv reception. He referenced my H20 and h24 and HR24 receivers as still usable. I will find out in a few weeks when we head out if his info was good.
