Think you answered your own question "lots of running around"
I did find the 2 way and 4 way splitters at Solid Signal which I can purchase. I am not real skilled at this but how do I figure out which boxes are on each one. I assume, if I turn on all the tv's, disconnect one and whatever tv goes out, that is that one? Probably should figure out a way to label them for future reference.
If I do this, I will not need any terminating caps. If I used two 4 ways would that make much difference? The reason I ask is that I may be adding another receiver in the near future? Not sure at this point when, but that may happen.
As to "maybe" adding another receiver, there are at least a couple of ways to do this.
Since your current loss is so high, I would first want to address this.
Does your CCK have two coax ports?
If so, then it can be configured in a pass through mode, so it doesn't require a coax for itself, but can be inline with a receiver. I'm currently doing this with mine.
If it doesn't have two, then it isn't a wireless CCK, but if/when you need to add another receiver, I would use a second 2-way splitter and connect it to the 2-way splitter you may get now. I'd still keep the HR34 on the first splitter, run another receiver & CCK off the second splitter. This way, the HR34 has the least loss, the double splitter is no more than a 4-way, but this would only effect the receiver connected to it, and all the others on the "other side" wouldn't be affected at all.
