I am looking to take DSS, cable, and regular antenna and attach them into one location where they enter the back of the house. And then distribute each of them over the same cabling to various rooms through the house. Can someone point me to a distribution panel or something that will solve this? Thanks ahead of time for your help. :)

You can do sat and cable with diplexors over the same cable but I have never heard of 3 devices over one cable but that doesn't mean there is not a way. You can't run sat with a regular cable splitter and most of those dist. boxes are really cable splitters with boosters built in.

Echoslob is right. You can use a diplexer to combine, then separate, DSS and Cable (or antenna) signals, because the two services use different frequencies. [A diplexer is literally just a crossover, like you find in a speaker. Consider Cable to be the woofer and DSS to be the tweeter (ignoring the DC part of the DSS signal).]
Cable and Antenna use the same frequency ranges, so you need separate cables for them.
If you decide to modulate a signal, say a DSS audio/video output, to a channel, then you will need another cable for that (presuming the modulator is at the DSS and not at the head end).
If I don't have a decorator problem, I usually use a piece of plywood to hold the antenna/cable distribution system, and put it in the attic, or in the garage, or at least as high in the closet as possible. I have avoided the distribution panel because today's perfect panel will probably be too small tomorrow. I learned that in retail, where change is inevitable and you have to imagine how much more space you might need in five years without knowing what will go there.

All in all, you will have to double your cabling to do antenna and cable. It makes sense these days to wire with double cable, though, because we can get cable but we can get DTV over the air in many locations.

Please let me now take a moment and be a left-brained curmudgeon: please call RF RF, and call Video Video. You are asking about RF. Pummel manufacturers who offer video switchers that only have F-connectins, because these are not meant for video, but for RF. And Video needs to be called composite, S (AKA Y/C), Component, and VGA.

A good answer is easier with a clear question giving the make and model of everything.
