There is a 1 in to 4 out way splitter in the attic, and when I unplug 2 of the out cables, the signal is better...
So can anyone suggest a better 4 way splitter, or other ideas?
Well first of all, the fact it gets better JUST by unplugging 2 other cables, tells me it may NOT be a splitter problem, per se. Regardless of how many (active) cables you have connected to a splitter, it STILL "draws" the total signal down to whatever (remaining) sets you have connected. The fact it gets better by disco'g lines, tells me you might have some sort of issues on those other drops. (bad cabling, connectors, shorts, etc.) Those kind of issues (on other lines) can cause problems back through the splitter, & through the other lines/sets.
Assuming you really use those other (2) drops, you're going to need to thoroughly check those outs; maybe replace bad connectors, wall plates. Maybe it's old cable that should be totally replaced in the first place.
If you are NOT using all 4 ports on the splitter, then you should get a smaller, appropriate splitter & ONLY connect the drops you're actively using. That right there alone might solve your problems...
