Nah, I doubt it, because the last thing I did to solve my issues was
to replace the 4-way passive splitter (with the two unused ports
terminated) with a 2-way passive. prior to doing that, even after
replacing all the cable, I was still getting pixellation on a couple
of the HD channels on the TV in the basement. I just went to all this
trouble because a) I knew the stuff was OLD - when was the last time
you saw *tan* coax? and b) I didn't want the cable co. to have any
excuse to charge me if I called them out to troubleshoot and it turned
out to be something inside the house. As it turned out after I
replaced everything I got all channels loud and clear.
I imagine that if I ever had got around to pulling cable drops to the
bedrooms that I would be back where I started - not sure if it would
have been possible to ask the cable co. to turn up the gain a little
so I could continue to run a passive splitter or if I would have *had*
to go powered, simply because I never investigated it.

Hey, I can't comment on your experience. I can only comment on mine,
and what didn't work, and what made it work. The "cable guy" looked at
the cable that was initially installed (by rogers, 20+ years ago) and
said simply "that will have to go", went out to the truck and grabbed
a roll of the "good stuff" along with the compression style "F"
connectors and the installation press used to compress them. In a
matter of less than half an hour he had the new cables in for the main
floor and basement, and he pulled on the cable that went upstairs and
asked "where's this go?"
I said "upstairs".
He asked "pulled or stapled?"
I said "pulled"
He said "let's do it" and he put a coupler between the bottom end of
the old cable and the new cable and said "go give it a pull".
Within less than 15 minutes we had the wire up to the upstairs - all
the cable replaced - and at NO COST.
Then he took a look at the 6 way (IIRC) splitter that had been
installed by Rogers about a year or two earlier and said "we can do
better than this" and came in with the 2 3 ways and cascaded them in,
ran the modem power test, and told me that should be the last cable
trouble I'll have for a few years.
I think that was about a year ago, and it's been 100% trouble free
He said the high frequency digital signals and 80% shielded wire just
do not work well together. Needs to be 100% shield - that's foil and
braid, not braid only.
You need to remember, there's over 100 channels, likely 20 or more of
them High Def, PLUS the internet on that cable - and in many cases

perfectly. I explained to him that the existing cable was only 3

second approach is best, even if your 1:8 splitter is amplified, your
cable modem is a bidirectional signal and most splitters only amplify
in the forward direction so your upload speeds may suffer with the
config as you have it. With 1:2 passive splitter up front you don't
have that issue.

FYI: Cable amplifiers that handle bi-directional needs are common
now. They provide a path for the return signals (low frequencies) to
bypass the amp in the return direction. I believe some even amplify
the return signals. I almost bought one a few years ago, but then
solved my problem a different way (new cable into the house to replace
the one sliced by the condo association landscapers) so I have no real
experience with the bi-directional amps. I just know they exist.

Not to ignore your questions, bu, based on things someone else didn't
a) Be aware that a splitter decreases the output strength by the same
factor whether you are using all the outputs or not. That's probably
why they suggest using a 1 to 2 splitter at the start, because that
means your (one and only) cable modem will get a pretty strong signal,
as opposed to one that is split between 8 outputs. Of course if
you've already done it the other way and it's working fine, this might
be just a theoretical question. OTOH, it may be "working fine" but
still at a lower speed than you might want for your computer
b) be aware that a) you have to have a terminating resistor screwed on
to any splitter output you are not using or it further decreases the
signal coming out of the ones you are using.
