Wasn't trying to correct but offer more info as to why there currently is not a domed portable dish option for DirecTV like Dish and Bell have.
As for Ka band frequencies and SWM question, from what I know, there is no connection between the two. SWM did pose a number of issues when it was first introduced but that was more a hardware incompatibility with many receivers and LNB's currently installed than it was what frequency was being used to transmit or the dish size itself. But as the years have gone by, most dishes, LNB's and receivers in use today are SWM compatible so it isn't the issue it used to be. The Winegard G2+ is a good example of this. Although it can only do SD for DirecTV, it is compatible with all HD SWM compatible receivers currently in use.
As for DirecTV not wanting to move to Ka band frequencies, I can't speak to that for sure. But given that most newer sat's being launched by DirecTV are configured with more Ka transponders than Ku (DirecTV 14 has NO Ku band transponders) and instead have newer "reverse band" transponder arrays for 4K broadcasts, that just supports my suspicions even more. And although DirecTV 15 has some Ku band transponders aboard, I think they are more for non-US customers (Puerto Rico, Mexico or Central America) than for use in the US.
So unless there are some major improvements by companies like Winegard to figure out how to use the smaller dish sizes and still maintain acceptable signal strength for Ka band frequencies, I suspect the domed dishes for DirecTV will be obsolete in the next few years.
