Many splitters have a DC passthrough. Even some cheap under $10 satellite TV splitters have this. >From memory, I think you can disable the antenna supply on the Oncore, you don't want all three GPSes trying to supply DC power. I looked at the graph. It is such a clean jump that I doubt this is noise at the antenna. Also it looks like 50nS of noise. Seems to much for an MT12-T. Are they running in position hold mode?
