The house I'm living in has two cables that run from the outside wall
through the attic and into the living room and master bed room
respectively.
I'd like to add cable to three other bedrooms in the house. The
question: Can I splice one of the cables within the attic, attach a
four way cable splitter to it then run the wires (the fish tape aspect
doesn't seem like fun but there is plenty of space in the attic so it
seems doable) to the remaining bedrooms?
Is it possible to estimate the signal loss going this route? I plan
to run the 'in' from the outside wall to the 'in' on the splitter.
then all four 'outs' will get routed to the four bedrooms.
Thanks in advance

Sure. That's what an installer might do. He might also do it outside the house,
adding splitters as needed, and drill through the outside wall at each bedroom.

IIRC, the last cable installer told me about -7dBmV per splitter. If you have
digital phone, that will suffer first, because it needs a cleaner signal. An
in-line amplifier BEFORE the splitter may boost the signal enough to keep it
clean if you need more.

An amplifier in front of a modem has to be two way. I had one in the old house,
but the cable guy
took it off. Seems like it may have caused a proble,

Amplifiers increase the noise as much as the signal, or more if it's a
cheap amplifier. Cable modems and other digital devices need to be
connected to the strongest signal available.

Right. Amplifiers are only good for making up for losses *after* the
amplifier.
