Cable as in 'coax cable'- a seperate issue from the decoder box. It
amplifies trhe signal stength of whatever is going down the wire. I've never
had any luck with them, personally.
Coax hasn't been used for ethernet for years. An extra cat5 run to each
room, from wherever the cable modem/router is, or just get a wireless cable
modem/router, and a card for each PC. Most cable internet companies assume
wireless these days, and discourage wired systems. Makes life easier for
Ir is there some other reason for this? I feel like this is
If you want wired ethernet, yeah, they need to be 'home run' to a central
point. A wall-mount router or hub next to the telephone wiring, which should
also be home-run instead of point-to-point, and then an upstream link to the
server or cable modem.
Properly installed coax runs normally do not need an amplifier unless there
are more than 5 outlets per house. That number may vary from different
providers based on the signal they push down the wire. Generally the cable
company will sell and install an approved unit at a nominal cost if you need
one. It is normally ageist their TOS for you to install an unapproved
amplifier on their system.
Running the second cable to one room or a closet might be a good choice
since you have no basement. If you have enough wire and want to run it to
more than one room.that is okay also. The internet connection is split off
the main line at the entry point and it and the TV signals travel separate
The last time I bought this stuff, 11-04, I bought 1000 feet of cat5 and 500
feet of coax for $130 including tax. Overall wire is higher now but there
is not a lot of copper in either of these. I completely did a small house
and have enough left over for a couple of more. What I am saying is that if
you buy it right, it may not matter how much you use. The labor is
virtually the same either way.
The labor issue is a big concern. I was sort of assuming the variable
expense would be in the materials more than the labor. I assume that
running 2 lines from point A to point B vs. 1 costs about the same.
Meaning I need to plan this well so I don't have to have more lines run
down the road -- thus my inquiries.
Why can't you DIY? There are no licensing requirements since it all very
low voltage stuff.
I would be happy to explain the process. Tool needs are minimal.
I suspect you are going to have a real case of sticker shock when you get a
labor price. Nobody likes working in crawlspaces and most don't like
snaking wire inside walls.
Depends on where you are. In CT one needs any of several classes of
electrician's license (which require 2000 hours of supervised, documented
work experience to get) or to be employed by a recognized telephone or
cable company to install low-voltage cabling. This does not apply to
homeowners working on their own residences.
Peer and beam is pretty common around here so the expense shouldn't be too
great. I'm not crazy about nosing around in my crawlspace. My attic is
even worse. Only 4 feet of clearance in the very center and blown
insulation everywhere. I'd love to get rid of that and start over with
sheet. Another post perhaps...

In that case, you will need a big splitter at that single location.
Splitters divide the signal so you get a weaker signal at each
location. It may be too low, requiring an amplifier ahead of the
splitter (better than amplifying each output separately). A 4 or 8
output amp is just an amp and a splitter in the same package.
Connect a cable modem before the amp.
Best to have your cable modem and router at this central location, and
use CAT5 for distribution. It can be run alongside the cable to each
You mentioned wireless. A wired network will be simpler, faster, more
secure, easier to set up (referring to computer configuration), and
more reliable. When you're installing cable it would be a good time to
put in network cables too.
No, because the CAT5 cables will all be run to one point. It's a good
idea to put the network hub (along with modem and router) at the same
location as the cable distribution point. Use that for telephone too.
#2. Not only ok to run side by side, but you can buy it as one cable.
#3. Ok to go point to point if it doesn't interfere with other things.
Avoid running parallel to electrical cables.

Avoid series runs for POTS, its way harder to troubleshoot when you
have a problem, homeruns are the way to go!
Consider satellite for TV with its DVR digital video recorder service,
Elminates having to watch commercials ! it changes how you watch TV
YES! And there's a lot to that besides commercials (although it IS
nice to be able to skip over some of the more offensive ones).
BTW, I've had a DVR for about 7 years and often don't know the time
what I'm watching is on, or what channel.
Since labor is likely to take the lion's share of your money, I'd
seriously consider having an electrician take a look at your house and
see what it would take to install grounded sockets, perhaps upgrade the
service and add circuits where needed. Then the cost of doing the
signal wiring at the same time will be minimized. I'd worry more about
the electrical than the data.
with our Dish DVR it doesnt matter when the show is on, or what time it
gets moved too. the receiver automatically looks for the name and
shows magically appear on a list of available ones.
A hour of prime time shows is 15 minutes of commercials which we skip.
while a interesting scene or dirsurbance we can skip back and watch it
again. dogs barrked, phone rang neigbor stopped by.
DVR is THE BEST device we ever added here!
Or even what channel it's on, if set up properly on a DVR that
supports it. I don't know about Dish, but ReplayTV calls that feature
"theme channels" and TiVo calls it "wishlists".
Yes. Automatic channel selection on the receiver, is a necessary part
of what a DVR does.
I wouldn't use the word "magically"*, but yes.
Approximately, on most channels. A PBS show is closer to 55 minutes
Also, TV shows and movies often involve things (signs, maps,...) you
could read if you got to look at them long enough. You can actually
read the wordy introductions to some movies.
BTW, I actually wished for something that would do that, for years
before DVRs existed.
Yes. I've had one since 1999 and would NOT want to have to live
without one. About the only time I watch TV without a DVR now is when
I'm on the phone (or in a chat room) where people are discussing the
show in real time.
* - many times, "magic" (NOT referring to stage magic but the "real"
thing), and it's synonym "supernatural" are often used as excuses
rather than explanations. The words have little or no meaning
We start watching some shows like survivor 15 minutes after they begin.
This enables us to FF thru commercials and be caught up to live at end
Cant do that with a VCR
People without DVRs dont know what they are missing!
I am not sure where you are now but if you want to put in grounded
circuits for your TV, computer and such you should pull in a Romex
while you are crawling around down there.
Surge protectors are not as effective (or effective at all, some say)
without a good ground. Take it all back to your service panel and the
ground electrode for the system. Make sure the cable and phone company
use the same electrode. No use wiring all this up and having it smoked
the first time you have a thunderstorm..
I wouldn't tywrap thew power to the low voltage but don't get your
panties in a wad if they are close together. Coax and Cat5 are very
good at rejecting 60hz and the little spikes you may see on a Romex,
particularly when it is dedicated to the same equipment the coax/cat5
is going to. In fact they make NMS cable with low voltage and line
voltage in the same jacket.
