I'm just relaying what the tech observed. The cable run in the attic is basically in a summer roaster and after, what, twenty years (?) the heat maybe has gotten to it and the impedance finally just hit the "straw that broke the camel's back" moment. I don't have a hard answer at this point. I don't know why the Cox tech from years ago put a splitter on that line, but he did. We will see if the new run fixes the issue.
I completely understand the purpose of a splitter; my point was that there was no *need* for a splitter on our setup. There's just no rationale for it - feed should go straight to the drop in my office. And Cox was the one that put it in years ago.
A splitter is a device used to split a cable
Good to know!
