Unfortunately, Scherrman, the diagram you posted states on the bottom "if you did not download this document from" Tom Hughes's website, it "may be out of date." How does Tom Hughes = Echostar?
And five is an unusual (I was going to say "odd" but that's obvious) number of devices to split from two feeds from the Hub. I could see two, I could see four, and I can see six, but five would mean one (no splitter) and four (4-way), or two (2-way) and three (3-way). Asymmetrical.
I'm inclined to go with Scott's "word from the horse's mouth." In any case, it doesn't matter in my home as I'm only looking at a single 4K Joey. Six Joeys is massive overkill. Maybe those $500,000 houses with HDTVs in the bathrooms...
