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

I want to split my best 5 Volt GPS Antenna among several Time Standards Systems (some 5VDC and some 12VDC). I can get inexpensive Satelite Splitters (2GHz) from Radio Shack or Monster makes a 4GHz Splitter. These splitters are 75 Ohm but my Antenna and Receivers are 50 Ohm. My question is how mu
