In any event, there is no use in trying to get above a certain threshold until you know what the minimum threshold for a specific make and model of a tuner might be. Perhaps the Roamio is a "20" or a "30" or a "55", or whatever, I don't know.

Maybe some modest amplification might help, but there's a whole bunch of information that hasn't been provided that is needed to analyze the distribution system.
It may sound strange but I am in a "wait and see" and "trying to confirm this is the best setup for picture quality/no picture issues etc." I attached a jpeg file of what my setup looks like after they got done. What the diagram does not show is a Tinlee AC7 combiner for Channel 49 Fox that they took out (for whatever reason they thought is was causing a loss of signal). My main purpose for bringing out the help was to create the moca network that is separate from the Tv signal network. But, I was wanting them to explore whether some additional amplification could help clear up some of the picture issues I had been seeing at times like small cutting out of the picture I have been seeing on the screen at times (the system had to be adjusted anyway to just send the TV signal to the Roamio connected television).

The Roamio has a "signal strength" meter that can be accessed as well as a "DVR diagnostics" menu. The DVR diagnostics goes beyond just signal strength and gives SNR and other information. So, I am guessing the information is the same as the Premiere. If you could tell me something to check for, I can do that.

I would like to go back to my original question about whether they or right regarding the amplification and thoughts on the setup in general.

ADTech, have I provided enough information to better analyze the situation?
