In your setup posts, it might be good to have the lengths of cable listed. You might notice I have it in mine. This is because in the DECA adapter testing, there seemed to be a correlation between some anomalies and the lengths of RG6 between splitters, filter, and receivers/DECAs. In the RF domain, one DECA signal has multiple paths, so the same signal can end up being at different power levels, or the same but shifted in phase. Different levels should be easy for the DECA as it could simply pick the strongest, but if two are at the same levels and one is shifted 180º out of phase, the two should cancel. I like the term "DECA Cloud", from the start, as it describes the DECA signal paths quite well.
