My cable provider (rogers) did all the cable work for free, including
splitters. My main line comes into a 3 way wideband 5-1000mhz)
splitter with 1 3.3db and 2 7db taps. The 3.5 goes to a second 3 way
wideband splitter. One 7 goes to the cable modem, and one to the
digital TV box. From the second splitter, the 3.5 gos to the tv
farthest from the splitter, the 2 7db taps go to the basement tv and
the tuner card on my basement computer.
Both splitters are Regal model ZDS3DGH10 if that helps. All cabling
is quad sheild commscope RG6.

No, because then you have 3.5+3.5 plus 4 connectors - each pair of
which is something like 3.5db (total of ~14db) loss.for the digital
tv. The cable tech that did the install explained why he did it this
way - the cable modem is less than a foot from the splitter and the
cable modem does not need as strong a signal as the digital box. The
digital box has only 2 connectors and the splitter - and it and the
modem both finally work just fine. With digital they don't reccomend
wall jacks because the add another connector and its associated
You should definitely put two outlets in each room (on opposite
walls); I wish I'd done that. You don't have to make them all
"active" -- just the ones that will actually be used. Run all of the
wires to a central location, label them, and connect just the in-use
ones. You'll thank yourself when you rearrange the furniture and just
have to go change one connection at the central splitter (or, in my
case, curse the fact that you didn't install an outlet on *that* side
of the room).
Same with Cat5e/6 runs -- run them and leave them unconnected at the
wiring hub until needed. I suspect you'll never sit around and wish
you hadn't run a particular wire, but you will regret the one you
decided not to run someday.
Makes sense. I think the only drawback may be that this will be pre-wiring
for an apartment that I am doing over and that will be rented out to a
tenant. If I put 2 outlets per room, I think I would need to make them both
live because the tenant won't have access to the wiring hub area at will.
If you string splitters one after another, you'll need signal
amplifers periodically in the string. I put in my coax after the
house was built. I have a central location in my bedroom with two
strings leaving from there, providing signal to 8 locations, and where
every second splitter would be, I had to use a 110 volt signal
amplifier. I would never embed them in the wall even if it were easy.
Most of this is avoided by using a fully central location. Although
if hte power splitter ever fails (and I don't know how often this
happens(, if it fails completely, which I think it woudl, it will take
out every co-ax location and require the replacement of the main power
That doesn't mean your central location should be at your bedroom, but
what you should consider are two things a) distributing internet
radio from your computer to devices that make sound, and b)
distributing internet television from your computer to your tvs. My
friend is willing to watch a few tv shows at her desk, but I want them
to be everywhere I can watch tv, with good seating, bigger screens if
I ever get a bigger screen, and in the kitchen for when I want to
watch while eating.
I probably only have to run one coax from the office PC to the bedroom
central location for the tv, but I haven't done it yet, and I don't
know your situation and if there's a better way to connect the
locations. I would rather run speaker wires for the radio connections
than have to play the radio through tv's, which will put added wear on
the tv and use maybe 30 times as much current. Especially since when
I play broadcast radio, I may have the radios in 5 locations on 3
floors, for a total of about 40 watts. 30 times would be 240 watts,
and that's too much.
It will work, just remember, a 3-way splitter has two -7db outputs
and one -3.5db outputs. put the cable modem on the -3.5db output as
you will want the least signal loss for your cable modem and also if
you have VOIP phone service. The TV signal is not as critical
As long as they go up to 900 MHZ or better, you should be fine.
For cable, get a small (2 way) distribution amp instead of splitting
so many times, withe the DA you will not lose signal quality also the
2 way DA will support digital interactions. Mount the DA close to the
entry then home run each room from there with RG6 Quad Shield cables.
Also suggest you run a send and receive cable to each room so that you
can watch devices in other rooms by re-distributing RF.
I'm running gigabit speed on my LAN using cat5e right now, but for the
little extra cost I would do cat6 again home run from a central
Does a hard wired home LAN make sense anymore? I did that when I moved
into this house 10 years ago but WiFi would be my choice today. Heck,
had to use WiFi to connect to a basement computer anyway.
If you have analog CATV now you should bear in mind that digital CATV
may be just around the corner from your CATV provider. Those digital
CATV boxes (one for each TV) are must less forgiving when it comes to
splitting and the quality of cables. Rather than repeat, hear are some
