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.

Have you looked behind the wall plates downstairs? Perhap a band-reject
filter? Are you certain the cables from the attic don't go somewhere
else before going to the downstairs TVs?

To check continuity: first use an ohmmeter to verify that the cable reads
open-circuit at DC in the attic. Then connect a 1.5v battery across the
disconnected cable in the attic and check for 1.5v downstairs.

If all else fails, move the TVs up to the attic.

Try a female/female rf connector from radio shack. Bypassing the splitter to
see if it sends signal to each tv's



If that doesnt work, then suspect the cable from the Antenna to the splitter
is bad??? If it does work, get a new splitter.

*If* we take what he wrote above verbatim, I would suspect the cable from

this time include the antenna feed cable in the path. If it doesn't work,
it's that lead cable.

Sure, but since he already knows his 100' bypass from the antenna to the
TV works, adding just the lead from the antenna to the splitter would
quickly identify the culprit.

My brother had a similar problem. It turned out that at 1TV, the
connector was shorted and was the cause. I suggest that you unplugged
all the cables (except the Antenna in the input connector) and connect
only 1 cable at a time to see if you get reception. A portable TV at the
splitter would be great to verify that each output works.

I assume that your splitter does not need to be plugged in.

good luck

A four way splitter has a loss of 7db per port, so the signal from the
antenna is lost trying to go through the splitter. You need to install
an amplifier between the antenna and splitter to boost the signal level
up enough to make it through the splitter. The splitter worked for the
cable TV feed because it provides a much stronger signal than an
antenna.

You did not mention, is this for HDTV? If the cable is old like RG58
or 59, it might not be able to handle the UHF bandwidth of HD
channels. If the 100ft cable you tested was RG6, and it worked, that
would make sense. But as the other poster said, try testing the cable
and see if there is continuity.

What??? RG-58 is 50 ohm IIRC and while RG-59 isn't the best coax, it
will pass HDTV RF properly. The best of the RG-59 is Belden 1505 and
is nearly as good as RG-6. I would look for corroded connections at
every junction point and replace when found. Any rodents chomping
through the cables?

Every 4-way I have seen has actually been an amplifier - look at it
from all sides and see if there is a power connection: it would probably
be DC power from a 'wall-wart' located elsewhere.

No doubt. Won't work with cable either, at least not with my cable.
The former owner of my home was using that POS in the attic to split
the signal, and the picture on each TV was horrible. The cable company
installed a 6 way splitter/amp and that resolved the problem.

As another poster said first, a 4-way unamplified splitter just will not
work with antenna, althought it will work with cable. This leads to a
solution for the OP: get an amplified splitter OR connect just 1 tv,
which I think they did.

All above are *unamplified* 4-way splitters.

A 4-output 3dB amplifier.

Even if his splitter is good, this amplifier may serve as a good substitute.

I have a similar setup. Then I discovered there were two coax wires
outside. After connecting these, my high-def power attic antenna
works great. A continuity tester might help.

You have shown the antenna and downstairs TV are good. Something you
bypassed with the 100' cable is bad. Add parts of the bad system, one at a
time, into the good system. Suspect ALL connectors and extension cables
until they work with the good system. The splitter is the main suspect as
all four down cables shouldn't fail at the same time. The inline amp may be
needed to overcome the loss of a 4-way splitter but you should see something
without it.

I hope the house wiring is RF and not fiber-optic!

Does anybody know how I can get the signal from the antenna in the
attic to TVs downstairs?
Thank you.


You have shown the antenna and downstairs TV are good. Something you
bypassed with the 100' cable is bad. Add parts of the bad system, one at
a time, into the good system. Suspect ALL connectors and extension cables
until they work with the good system. The splitter is the main suspect as
all four down cables shouldn't fail at the same time. The inline amp may
be needed to overcome the loss of a 4-way splitter but you should see
something without it.

I hope the house wiring is RF and not fiber-optic!

A similar problem in my home installation recently was traced to a broken
center pin in an RG-6 connector. When I stripped the cable to install the
connector, I nicked the copper center wire. When it was pushed into the
splitter, the pin broke and continuity was lost.

A continuity check is a good idea.

You'd really have to work hard to make a passive splitter fail. I
guess applying 110 volts might do it.

That might have been true in the old days, but with tv's going blank
if the signal is too weak, I wouldn't count on it.

Lightning kills them by the millions. As an engineer for a major
CATV MSO years ago, I lost hundreds every month. They are simple three
port RF transformers, wound with wire the size of a human hair.

You're right. Oops.

Since the antenna is working (when bypassing the splitter), there are a
couple of things to look at. One possibility is that the splitter is
defective. Another is that the cable(or the connectors on the ends) from
the antenna to the splitter is defective. Try connecting the antenna to the
splitter with a different piece of cable, or with the 100 foot cable that
you know is good. If this gets the signal to your sets, then the cable was
the problem. If it still doesn't work, then I would say that the splitter
needs to be replaced.

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.

Reread the post, he has an amp. Now granted, it's not a splitter/amp,
and that might make a difference, but there are ONLY two
possibilities.

Either the cable from the ant to the amp to the splitter is bad, or
the splitter is bad.

My guess is the splitter is defective. Splitters are very inexpensive,
so try replacing it.

And old splitters were low freq. Replacing is a good idea.

Why is everyone guessing the same? The poster said:

also connected the antenna to
each of splitter’s outputs (which go to TVs) – exactly the same
outcome -

which discards the splitter as a possible culprit. It must be these
cables going downstairs.

If you are sure that the original poster means that he disconnected one of
the cables that goes downstairs and connected it to the cable from the
antenna. What he said could also be interpreted to mean that he
disconnected a cable from one of the splitter outputs and connected the
cable from the antenna to this output (which of course would do nothing).
Nothing surprises me anymore. Anyhow, I guess if all else fails he can
connect a known good cable from the antenna to a new splitter(plus amplifier
if needed) and run four new cables from the splitter down to his 4 tv's.
Not a terribly difficult job if you've done this sort of thing before.
