My wife has given me a project - move the TV in our upstairs bedroom
from one side of the room to the other. Right now, the coax outlet is
on an interior wall, it was installed by a contractor of the cable
company. The new location of the TV is going to be another interior
wall. I got up in the attic while home for lunch to see if I could
look down between the wall of the bedroom and the wall of the
adjoining bathroom, but there seems to be plywood laying over top the
opening (but not on top of the joists). Using our home security
wiring as a point of reference (the security control box is on the
same wall that I need to put the new coax outlet on), the installers
for that had drilled holes in the plywood to run their wires. There
is an unused phone jack on the same wall, I'm considering removing
that and running the coax through that box (it's not even really a
phone jack, just a small glut of wire stuffed into a little box in the
wall, hidden by bedroom furniture), but I am not sure if the wires
come through the attic, or come up from the bottom. If those wires
come through the attic, I'll try dropping the coax down the same hole
and hope for the best.

Anyway, any advice for someone tackling this kind of project?


Open up the unused phone jack and see if there is room to push a fish tape
up the wall. If there is then push a fish tape up to see if you have
clearance to the top of the wall. You can also use the fiberglass rods for
this which work well if there is insulation in the wall. If you are able to
determine that you have a clear shot to the top of the wall then go drill a
hole in the top plate of the wall. It is most likely not plywood, but a
single or double 2"x4". You can drop a lead weight on a string down the
wall if there is no insulation or push your fish tape down from the attic
and pull the wire up.

This has been discussed in this group before. Do a Google search for more
ideas. You should fill the hole that you made after the wire is pulled with
some sort of firestop material such as mineral wool and a fire stop caulk.
