There's a good article about connecting more than one switch/SWiM here: http://forums.solids...ers-in-the-home
One of the more advanced is:
To aid in planning losses and layouts before committing to this, here is a calculator that you can load coax lengths to get an idea of the DECA loss.
This works best with the longest coax connected to the same splitter, since the signal only needs to go through one splitter between the nodes.
Long runs on one splitter do effect the maximum length of other splitter runs.
In the jpg shown in post #1 (and above), if one had a position open on the 4 way splitters, couldn't you just interconnect the SWiM clouds from that point instead of using the 4 additional 850-2150s, which in theory would result in less signal loss?
