This may be the wrong place to ask this question, but here goes. I need to
wire the house for cable (TV). This is a peer and beam house with
limited attic space -- an attic install would require a hearty, short
person with a tolerance for blown insulation.
1) The cable TV installer said he couldn't do the job under the house
because he needed some sort of right angle drill bit. He said I should
call an electrician. What's that all about?
2) I figure I should run CAT 5 cable along side the coax at the same time
to be proactive. Can they coexist side by side without interference?
3) Is it cool to run the lines straight under the house from point A to
point B or should they snake around the perimeter, walls and beams to stay
out of the way? (I like to do things the right way if it doesn't double
4) My house has no ground wires running to fixtures or outlets. Should
this be done at the same time or is that a whole other mess to deal with
Thanks in advance,
CATV installers often do not snake wires or run them internally. They can be
run with Cat5 and terminated on the same wall plate. Electricians and alarm
companies often run these cables, snaked in walls . All your cables should
be home runs to a designated point, usually where the main line comes to the
building. Are your non grounded cables non metallic, and how did you
determine that they have no grounds?
It is called a lazy installer. Assuming you are putting boxes in the wall
this does require some careful measuring and moderate difficulty pulling the
Coax and cat5 are fine side by side. They can terminate in the same box.
You can even buy face plates that have a cable/ network or phone jack.
Direct lines are fine if supported. Along structual members or perpindicular
to joists is the preferred method. Note that all cable runs should serve
only one outlet (called home run) and should run from the point of entry to
the oulet. I actually prefer to run my phone lines in this manner also but
they are frequently ran in a series (from box to box).
If you are thinking you might want a wired network you should home run each
cat5 box to a central loacation where you can then configure the wires as
you see fit. Note that it not reccommended to use the same cat5 wire for a
data network and POTS. If you are thinking network or other communication
equipment this termination point should not be in the crawlspace (a closet
That is a whole different ballgame. Do one project at a time.
He (installer) offered to run it through the exterior wall but discouraged
that. I already have one hole in the brick where the AC lines run into the
house so I figured I'd use the same hole for the coax then get out the

My brother had me wait for the Verizon cable installer in Dallas, who
refused to put the computer cable in the room my brother wanted it.
It was partially prewired to several rooms and he did go in the
unfinished attic and connect a couple things.
When I discussed this at a Baltimore hamfest with a computer cable guy
(that is, a public relations guy with a booth.), he insisted that they
would put it whereever the customer wanted it, and the guy in Dallas
should have also.
I don't think he was trying to sell me anything, because I'd made it
pretty clear I wasn't in the market. In addition, it would be easy in
my house to put in anywhere.
As others have written, there will be no interference between Ethernet
and coax. In theory, direct point-to-point wiring will provide the least
signal loss but inside the footprint of a small house there is probably
not going to be much loss anyway. While you are at it, instead of Cat-5
cable you may want to consider Cat-6 to be ready for future needs. Of
course gigabit Ethernet equipment has come down greatly in price already
so right now might be the time to start using it. I'm seriously
considering re-pulling all of my Cat-5 before closing up the last
openings in the basement.
Unless you have a network of computers in your house, that regularly
transfer massive files,between themselves, you're wasting your time as your
bottleneck is in your internet connection, which is good for maybe 15
mega-bits per second
Mostly I'm using the CAT5 for POTS -- but I thought the extra capability
would be worth running that instead of CAT3. I've heard about CAT 6 and
will price that. If it's not too much higher then that may be the way to
go. However, if it's being used for the phone then I assume each line has
to be run to the main phone block, so it may not be worth considering for a
The other posters covered 1-3 well. I might add that you should use a cable
amplifier with 4 or 8 outputs and run one to each room where you can then
use a splitter. Avoid using splitters at all cost in the basic distribution
system and you will have a better picture all around. If you only went to
one or two TVs then a splitter would be fine but people rarely have such
simple networs anymore. A splitter in one spot or a two way amplifier is
needed if you have cable internet.
Splitters don't add noise (at least not white noise) but they divide the
signal until it is competing with the noise and can no longer be reliably
detected by the tuner. This usually turns up on some channels first as
ghosting or patterned snow.
4. No not at the same time, you don't even want the AC wires close to your
network or cable wires if you can help it. Rewiring ground is best done one
room at a time as you gut and remodel these rooms. I suggest adding a GFCI
to the ungrounded outlets you want a ground hole on for extra protection.
Its not a direct substitute for a safety ground but does provide some
overlapping protection against shorts to ground.
Now if you had the walls open for some reason, then yes, put in every type
of wire you think you might ever need.
What the heck does a cable amplifier do? I figured I'd need a cable box in
every room I want to watch TV in.
I figured I would run a single cable from the entry point into the home to
a single location in each room. Do I need something more than that?
If I want cable internet some day vs dsl should I do a double coax run to
at least one room and run the wireless connection from there? I can't see
needing a home network where every room is on ethernet, but now that I
think about it, I guess having a double coax run in every room along with
cat 5 allows me the freedom to set up the network hub anywhere in the
house, right? Ir is there some other reason for this? I feel like this is
going to be overkill at some piont but again I'd like to do it right.
Besides, if I run ethernet throughout the house it still all has to meet at
a central location -- wherever that is.
