Gentlemen, thanks again for all your replies. Everyone has been so generous with your time and sharing your knowledge. I have spent the last few hours doing more research and, as with many things, it’s more complicated than first thought. Compatibility is a big problem as technology advances so quickly. I found that out in my business once photography went digital. Top of the line camera systems became practically obsolete in 5 years.
My 2008 Allegro was one of the last years with analog SD TV’s. Since our RV trips are limited and we spend much of our time outdoors, TV was never a priority and we never upgraded to HD. So for now, a RF modulator would probably be fine if that, combined with the DPH42 , would allow me to use my current setup to view both front and rear TV’s.
Tom, you obviously have a LOT of experience doing this. Much of my research was reading your writing on the subject. I’m not clear on how to connect the DPH42 to the dish. The RV Tech who installed my Winegard system has always done great work with attention to detail. He ran one of the lines from the dish to the Winegard box, the second line plugs into the Dish receiver, and the third line is unused. Your wiring diagrams never indicate how the Winegard box is wired, or maybe they do and I’m just not seeing it. Can you please clarify? Thanks!
