I know that the cable modem must have a pretty strong signal so it can
be downstream from a few splitters.
But I need to put in at least one or two. Where the cable comes in (A)
I have a single TV. The modem is in the next room (B) where there is
another TV. I'm choosing between two options:
1. 2-way splitter at location A and a 2-way splitter at location B.
2. 3-way splitter at location A
Way 1 is neater, but perhaps the modem gets only 1/4 of the signal.
Way 2 is more cumbersome, but perhaps the modem gets 1/3 the signal.
So which way is better?
Many thanks in advance,
Really, where can you get a bidirectional amp like this. I was told by
my cable company I could not use my amplified distribution system with
my cable modem or cable box because of this and there was no amp
available that would fit my needs.
Commonly available. The reason the cable companies discourage using them
is because people buy them because they have a bunch of incorrectly
configured cheap splitters or have poor wiring. The amplifier just masks
the problem. When they remotely manage the equipment the levels will not
correctly reflect system levels.
Cable companies are typically pretty good about making sure there is
sufficient signal. Around here if you have signal issues they will
adjust them as required. Anytime I have seen an installation that seems
to need an amplifier it can be fixed by clipping off all of the twist on
coax connectors, terminating the cables properly and using quality
splitters that are arranged properly.

See TechTip #1 at bottom of page re use of "unbalanced" 3 way splitter
(1 port gets half signal, other 2 get 1/4 each)
I just installed a cable modem. The speed was okay but not great.
The cable company sent a tech out. He said they ALWAYS split for the
modem right after the grounding clamp. He put on a 3 way where there
had been a 2 way and ran a line directly to the modem. I have a TV
right near it and asked about putting in a splitter for that. He said
to use the existing (old) wire for the TV and to keep nothing but the
modem on the dedicated wire.
I have a signal booster for the TV (because the signal was not too
good) and picked up a two-way booster at Walmart. It turns out the
signal was bad because of the grounding clamp was bad. When he
replaced it it made a huge difference.
My buddy was asking about an amplifier. He bought one and there was no
improvement. I stopped by, clipped off a couple mickey mouse twist on
coax connectors and installed snap seals. Problem solved and no
Ok, my 2 cents. I had my modem connected to the output of the first
splitter, then I got the digital cable box. The cable box was hooked
to the second splitter. I found that the on-demand wouldn't work, so
I switched the modem and cable box. The modem is on the second splitter
and the cable box on the first. Now they are both working just fine.
