If the cable was daisy chained as was the custom years ago, there could
be a splitter at every outlet. My last house had a run with 9 splitters
in it. Needless to say, it didn't do very well with a broadband
connection!

Sorry for the newbie question, but what happens if there is a
splitter? Also, is possible to tell - and if so, how - if there are
one or
more splitters between the attic and the room?

And, another also, will the presense of one or more splitters affect
the other approach suggested by others on this thread
(volt-ohm/multi meter)?

At least thehick's other idea - using a portable tv - should still
work...

If there's another splitter, then it depends on the particular
splitter in question -- some will pass DC, others won't. If it
doesn't pass DC, then neither the buzzer nor the meter will register
the battery's voltage.

As for using a TV, it'll introduce some ambiguity there, too, since
you might have two (or more) equally good signals.

If you have the same number of wires in the attic as wall
connections, there's probably not another splitter.


If there were more splitters, it would be unlikely that they would be
hidden away somewhere. Splitters and connectors do occasionally fail
and they would have to be accessible for service. Depends on the
intelligence of the installer.
