Not in my electrical distribution box as well.
Can I clarify my understanding;
This main coax cable in pic below is found in SCV riser outside the house?
Each black cable goes to different household on that level?
The black cable will lead to this main splitter found in the house, which is the middle cable that the port indicated "IN" in pic below.
The other 4 cables lead to out to 4 other outlets in various rooms?
I can just disconnect this "IN" cable, leaving the rest of cable intact and resolve the signal outflow issue?
Where can I locate this splitter in my house?
It is not in my electrical distribution box or the riser it is in.
It is not visible where my intended TV is (only cable TV wall socket seen).
