I had DTV for years and used one of my receivers on the road receiving standard definition. It worked flawlessly.
I have just switched to dish for a variety of reasons, but will use my own receiver in a Pay As You Go no contract format.
It just works for me.
One more thing. Dish offers more technlogy than DTV does - and I was a DTV bigot for years. I can stream all that I have recorded on my home Recorder when I have internet service on my phone, computer or roku on my TV or my firestick.
Last DTV has said they are going to stop broadcasting in Standard Definition in April of 2019. In order to receive the signal you're going to need a different dish than the current standard 18".
