Hi Don -- I know of several folks who've used the satellite stuff with pretty good results, so I'd give it a try. I may be wrong about this, but my gut feeling is that you would want to arrange things so that the longest cable runs (with the most loss) would be terminated in their characteristic impedance, to reduce increased loss due to SWR (though it might not make much real-world difference). So, assuming the antenna is designed for 50 ohms, you'd use 50 ohm cable from the antenna to the splitter. The shorter runs from the splitter to the receivers wouldn't be as critical.
Hope this helps.
