The levels aren’t that high to the point you need action imo. Plus if you put that sim in and your provider changes their diplex splits to say a mid split or high split, that antenuator will stop you from seeing some of the upgrades. But yes that will work
I was under the impression that for DOCSIS 3.0 the preferred range for downstream power levels were anywhere from -/+10 dbmv with closer to 0 dbmv with -/+5 dbmv was preferred? I am running an older Arris SB6141 but will likely upgrade to an SB8200 here soon.
Out of curiosity, how would the forward path attenuator prevent mid/high split from working? I was under the impression forward path attenuators only reduce the incoming signal strength without blocking any frequencies or affecting upstream.
EDIT: The 4 port splitter should drop signal by ~7.5db on each port. Theoretically my incoming signal is somewhere around 17db just before the before the splitter, but there are a few items that does not take into account such as: grounding block, moca filter, and the length of cable from the tap to the demarc at the side of the house.
