The short answer is yes, I use a 722K with a Winegard dome. The limitation is that the dome can only receive one satellite at a time so if you want to watch or record a second channel, it has to be on the same satellite. The setup still works for me because most of the satellite programs are broadcast at multiple times so if you can't record it at one time, you can usually record it at another time. It probably wouldn't work for me if I couldn't receive two OTA channels at a time on the Dish receiver. This along with a DVR+ that records two additional OTA channels means that I only have to use the satellite for satellite programs and not broadcast network shows.
There is one problem that has to be overcome when setting up a recording. Only one of the satellite cables (receiver 1) controls what satellite the dome is set to. Unfortunately, Dish always records on receiver 2 first and won't switch satellites if the dome was previously on another satellite. To get around this, I always schedule an auto tune program either just before the program I want to record or on another channel that uses the same satellite. The auto tune program on receiver 1 changes the dome to the right satellite and allows receiver 2 to record the program you want.
My preference would be to use one of the new auto satellite dishes that allow all of the satellites to be viewed at the same time. Unfortunately, domes use 12 volt power the the new automatic dishes need 110 volt and there is no way to run 110 in my RV to the satellite dish. In the past I tried carrying home style dish but was more of a problem setting up than I wanted to deal with. Since my dome is on the roof, I do carry a carryout dome for when the sky is blocked by trees.
