I have a Satellite receiver that pickes up a few
channels from overseas. I put a 1x4 splitter on
its output to route this signal into 4 rooms. The
standard television sets in other rooms handle this
signal perfectly. But one room has a "TV BOX" used
for routing a television signal to a computer monitor,
in this case a flat screen LCD. This line seems
to return a rogue signal to the satellite receiver
that somehow messes up the master signal going out
from from the receiver, resulting in all 4 split
legs performing poorly. Can I put an rf isolater
or circulator on the offending line to improve overall
system performance? Recommendations?

I would try to an attenuator first. Try a 3 or 6
dB. Or an amplifier and attenuators.
If you
have an isolator that work at those frequencies
of course you can try that too.
Be sure to
terminate the unused ports.

If your coming out of the receiver then you are
low frequencies. You can try placing an amplifier
on the line (Radio shack cells them) to isolate
the path. Most amplifiers will gve you as much if
not better isolation than an isolator.
