I require a second coaxial cable to be run into my finished underground
basement (from a second signal source). I've posted a photo diagram
(http://snice.net/basement.jpg) to illustrate what I'm working with.

As you can see, the outside wall is concrete foundation, which prevents an
easy drilling solution. My guess is that the existing cable was run when
the basement was being finished. Now that the wall is finished, what are my
options for installing a new jack alongside my existing one? Having a jack
high on the wall isn't acceptable to me for aesthetic reasons. Can it be
wall-fished, or is my only option to dig alongside the foundation and drill
a hole at the desired spot? If so, does drilling the foundation
significantly comprimise the structural/watertight integrity of the
foundation?

Thanks for any input.

To do the fishing your going to need a hole on the outside big enough for
the cable. This bothers me some because of water and cold coming down the
wall. A 1/2 hole is no biggie, sealing it will be.
Drill the hole, drop some jack chain down the wall and have some one move
the jack chain till you locate which cell it is in. Cut your box hole and
acquire the chain. Tie on the cable pull it in.

If the wall is insulated with fiberglass with some time and a fish tape,
electrical tool you will be able to locate the tape pull up a cord and then
down with the cable.

If the wall is insulated with Styrofoam or hard board. It is time to slot
the drywall and patch and paint.

I have no technical expertise in this area but to me it just sounds
like common sence that you do NOT want a hole in your foundation wall
that might let water or insects in. I doubt it would affect
structural integridty of the foundation but any hole/crack below
ground level will mean water leaking into the house. you don't want
that.

You said you were thinking of digging down along tehe foundation and
drilling at the appropriate spot. I would have thought that drilling
above ground level and then just redoing all the drywall behind the tv
(so you can run the cable behind the wall and down to where you want
it) would actually be much easier in terms of time and hassle. You'd
have to dig down about 5 feet. And make it wide enough to work in.
That's a hell of a hole.

Depending on your application you may find that your one coaxial cable can carry both
signals. What exactly are you trying to do?

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
cable around the baseboard of the room. You can use a T-25 staple gun to
hold the cable in place. Just make sure you do not bite the cable with the
staples. This is the way most cable, alarm, and telephone companies do their
installations.

You could try coming through at the top of the foundation adjacent to the
bulkhead on the top left of the image then running some surface mount
conduit like
http://www.wiremold.com/www/consumer...ate2/index.asp along the
corner then along the baseboard to the tv. You could also do that on the
right side along the post. You may also be able to run your surround sound
wiring in that conduit. I believe it is paintable too.

Running the wire high means you might be able to drill through the sill
plate (wood) as opposed to low which means digging and drilling through
10-12" concrete.

Another thought is going through the window framing then using the conduit.
