Interestingly enough, I moved the Myth backend to it's usual home, in
the basement, right next to the incoming cable signal and replaced that
25' run that I had going to where it was temporarily with a smaller, say
10' run (of RG-59 so still room for improvement) and my SNR at the
HVR-1600, even after all of the splitters is now "015c" or 34.8 dB.

I'm still going to go replacing all of that RG-59 with shorter, custom
made lengths of RG6 cables.  I can't go "too short" when making those
can I or would even a 6-12 inch cable be perfectly fine?  I'm thinking
of the runs between that last 4 way splitter and the tuners in the Myth
backend.
