How to Run Cable Wire in Your House
Running Cable Wire between the Main Cable Line
and a Finished Drywall Location
By Mark J. Donovan
Running cable wire in your house can
be fairly easy if you have access to a basement or attic. It also helps if you
only need to fish the cable wire from one level above (e.g. just above the
basement), or from one level below (e.g. just below the attic). Running cable
wire up or down multiple levels within the home however can be nearly
impossible, without having to remove some drywall. If you have the opportunity
to plan and build a home, put a little extra time and thought into your cable
wiring plans. My recommendation is to run cable to all main living areas and
bedrooms. You may also want to consider running cable wire to even the
Attach Cable Splitter to Main Cable Line
To run cable wire in your house first locate where the main cable line comes
into the home. From there cut the main cable line and attach a cable splitter to
the end that enters the home. You’ll first need to attach a coaxial end
connector to the main wire entering the home before you can attach it to the
cable splitter. Also, make sure to attach the main wire to the input end of the
Then attach a coaxial end connector to the other end of the cut cable wire and
attach it to one of the output ports on the cable splitter. You should then have
one or more output ports on the cable splitter to connect additional cable lines
Install Remodeling Box in Room for Cable Wiring
Next install a remodeling box in the wall where you want the cable service. The
remodeling box, a.k.a., old work box, is a special type of electrical box that
is designed to be installed in finished drywall.
You can use a drill and then a
drywall cutting saw to cut an appropriate sized rectangular hole for the
Running the cable Wire in Your House
Next measure the distance between the cable splitter and the remodeling box.
Make sure you also account for any required turns or special routing of the
cable wire in your measurements.
|Then cut an appropriate length of cable wire and run it between the remodeling
box and the cable splitter. I always prefer to run the cable wire starting from
the destination (e.g. remodeling box), to the source, the cable splitter.
To run the wire you may need to cut a hole or two in a subfloor or through a 2x4
top or bottom wall plate. I suggest using a ¾ inch cutting blade drill bit for
creating a large enough hole to fish the cable wire through easily. A modified
coat hanger can also come in handy to help fish the wire through a wall.

Connecting the Cable Wire Ends
Connect the end of the new cable wire to the cable splitter after attaching a
coaxial end connector to it. Then connect the far end of the cable wire to the
back side of a cable connector wall plate. Again, you’ll need to first attach a
coaxial end connector to the cable wire before attaching it to the back side of
the cable connector wall plate.
Lastly attach the cable connector wall plate to the remodeling box with a couple
of screws and your cable wiring project is complete. Attach a television to the
new cable outlet to confirm that cable service is now available to it.
