In your case, you would probably be better off to call the cable company,
and let their experienced installation people do it for you. If you want to
run this in yourself, and if your inside walls are paneled in a fashion
where there is a space between the wall and concrete, you can run possibly
the cable between, depending on how the joists are put in. In new
construction the cabling is generally put in before the panels go on.
The way that it is done most of the time, is that the cable is run along the
baseboard, and or through the ceiling, and comes down behind a wall panel
out to an F51 connector plate. How it can go in is very dependent on the
access for it to be run. If the cable feed is to be passed down on the
outside of the wall to the floor level, you can also get small conduit for
cable and telephone wires. These can mostly be purchased at most hardware
and electronics parts supply stores. The hardware stores will mostly have
the conduit for electrical wiring, but they are about the same anyways.
I would not suggest drilling through the concrete if the hole is going to be
less than about 2 feet above the outside ground. If a hole is made, it
should be made exactly the correct size for the cable, so there is no chance
for any insects or outside air to come in. It is possible to stuff the hole
with a non acid RTV or the equivalent insulation before passing the cable.
You can also put some extra RTV around the outside of the entry of the
cable. The remaining RTV should help to insulate the hole.
If you have a cable run inside already and want to feed a second TV set from
the same cable company, you can use a simple splitter, and run the second
