I believe that there are 3 dome units that support DirectTV (along with DISH & Bell via a DIP switch on the unit)
Most domes have gone to DISHnet. It’s just a better system for RVers.
But if you must have NFL package then you need DirectTV.
Also, note that DirectTV mostly broadcasts in SD with dome dish IIRC.
Whereas, DISHnet is primarily HD.
Also with DISHnet RV package you can turn on and off if you decide not to use it.
