I'm unemployed, and bored out of my skull. I spent about six hours yesterday with SketchUp drawing out what I would do if I had to view my 722 from an SD TV with nothing but a coaxial input.
I've read the manual, seen the PDF files, and it still took me a long time to grasp the topology of the RF wiring necessary to combine an OTA signal with a multi-satellite dish, diplexers, and backfeeding.
Here's hoping that this series helps somebody out.
First, I drew the simplest wiring I could devise. The problem with the first one is that it doesn't account for the bend radius of RG6, nor the physical layout on the back side of a 622/722 receiver. The second drawing did account for that, somewhat, but realizing that there was a better way still, I didn't render it in 3D. The final drawing is almost exactly the way I want it, except that it shows the mounting plank in-plane with the receiver, instead of perpendicular.
I conceived this as a 16-18" long 1*4" plank screwed to the back of an entertainment center. The PURPLE and RED lines MUST be 2GHz or better RG6, but you can get away with lesser cable (that's easier to bend) for pretty much everything else. I drew the diplexer, separator, and splitters as 2*3" blocks, which is ridiculously oversized versus real parts. But in real life, RG6 doesn't like to bend tight radii, so the wide spacing is helpful.
Google SketchUp is 3D modeling software that can be downloaded and used at no charge. I'm no expert with it's use, but if you want to twirl these drawings around in a 3D environment, this is a great tool. The original drawings are 1.78MB uncompressed, but fit into a 685kB Zip file.
