Default Need help - no signal from TV antenna in the attic

wrote:

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.
