Hi,
I just moved in to the new house. There is a 4-way coax splitter in
the attic, which has one input and four outputs (to different rooms).
I know that previous owners had a cable (from the cable company). It
looks like the cable was going into the same splitter in the attic,
and then routed to rooms downstairs.
I want to use the TV antenna in the attic.
I tried connecting the TV antenna to splitter's input – absolutely no
signal is getting to TVs downstairs. I also connected the antenna to
each of splitter’s outputs (which go to TVs) – exactly the same
outcome - not even a change in a static when I plug in the antenna.
I bought a TV signal inline amplifier from RadioShack – absolutely no
difference.
However, if I drop a 100' coax cable directly from the antenna in the
attic to the TV downstairs (bypassing the splitter and all of the home
cable wiring), the picture is crisp and perfect.
Can I run some tests to ensure cable continuation (from the attic to
rooms downstairs).
Does anybody know how I can get the signal from the antenna in the
attic to TVs downstairs?
Thank you.

You can't run four tv's off of a non-amplified antenna. I'm surprised
they could run 4 tv's off of cable without putting in an amplifier
somewhere. I guess I'm wrong about that, but the cable signal is
stronger than a passive antenna signal. Get a radio shack tv signal
amplifier with one input and four outputs. You'll need to power it
with AC.


I agree it is preferable in his/her situation to get an amplifier but it is
just "NOT TRUE" that a non amplified 4 way wont work. I am doing just that.
My house has a four way splitter, I just placed a Yagi antenna on the roof, an
old school Radio Shack Model VU-90 XR to replace an older model.

I am running it down from the roof, with approx 35 feet of RG6U/Q quad
shield, into the built in house wiring from our 10 year old home. There is at
least a few hundred feet throughout our home and most likely its only RG59
cable to boot. And i get perfect analog and digital signals with this setup. I
DO plan on eventually replacing all the internal cable with RG6U/Q when i can
get aroung to it. And i do plan to add an amplifier to the system at that
time, but there is not one channel in Salt Lake City that i cannot get.
