There is a cable television line that enters from outside into our basement.
The first device the cable connects to is an in-line Viewsonics VSGB1GTSS.
The Viewsonics VSGB1GTSS is not a line splitter, so I'm assuming it's a
signal booster of some kind. The second device the cable connects to is a
Signal Vision 2-way splitter SV-2G 5-1000MHz, with two 3.5dB outputs.
My goal is to run a third cable line off this line. Thus, I will need to
change the 2-way splitter to a 3-way splitter. Is Cannel Vision a good brand
for a 3-way splitter? Will I need to change the Viewsonics VSGB1GTSS to
match the 3-way splitter?
A google search did not show any match for VSGB1GTSS, so I am curious as to
what it is. I have a Viewsonics amplifier in front of me, a VSA-601L. Tell
me, does this VSG... have a power feed to it?
Anyway, any good 3 way splitter should do the trick, and you can put in an
amplifier if necessary. Get the 3 way splitter and just see how the pictures
How's that for a high tech answer!
ps. can you verify the VSGB... number, or get a little more info from the
device? You have me curious.

I don't know, but I would try it without changing and see how it goes.
I only have experience with one house. They had cable boxes when I
got cable and I wanted the cable guy to put the box in the closet. He
wasn't sure it could be put 8 feet away, when usually they were less
than 4 feet away, next to the tv. It worked fine, and later I had
occasion while snaking to run the cable to the front of the house, to
the back, and to the front again, 120 or a 150 feet. It worked fine.
Now everything goes into the VCR and out again. There's an amplifier
there with A) a short line to the bedroom TV, B) a line up to the
attic, a splitter off that line down to the bathroom TV, and the line
ends at the TV in the office. C) through the floor to the living room,
where ther is a splitter to the living room TV, through the floor to
the basement where there is a power amp with two outputs I) to the TV
in the family room, II) a line that goes to the laundry room TV, with
III) a splitter off to the kitchen (up through the wall from the
I didn't do all this at once of course. I didn't put in a power amp
until the picture was getting weak somehow, bad synch or weak color or
something. Everything was cheap. Everything works fine. A dollar for
the 2 in 1 splitters. The power amps from RadioShack, one their
smallest maybe and one one size or two higher. I found a wireless
device that lets me control the vcr from the remote from any room in

Is it powered? (probably a "wall wart" AC adapter?) If not, it
can't be a booster or amplifier, they're "active" devices and need
a power source. If it's just some kind of tube, etc, with no
powering, that's a "passive" device, usually some type of filter.
But in any case...
You don't necessarily need to use a 3-way, you can buy another
2-way and a coax jumper and feed it from one of the output ports
on the 2-way. You will be creating your own 3-way, it will work
electronically the same exact way as a 3-way will.
Point to realize about a 3-way: There is one "low loss"
leg (-3.5 dB) and two "high loss" legs (-7 dB) IOW, you lose
3.5 dB every time you split the signal. Put your most distant
feed from the splitter on the low loss leg.
Forgot to mention: The brand of the passive 2- or 3-way splitter
doesn't mean a whole lot, just make sure it's rated up to 1 GHz
(1000 MHZ) if that's what your cable co is currently installing.
You could possibly find some rated as low as 300 MHz, which would
roll off many of your higher numbered channels.
