A six way splitter has 11dB loss (or thereabouts -
it's somewhere between 7.5 and 11 anyway) which is a
lot to lose, especially on a weak signal to start
with.

Installing a signal amplifier will only work on a good
signal - a noisy signal will just cause the noise to
be amplfied.  In fact, I found that with my PVR-500, I
actually get a better signal if I take out the
amplifier/splitter and hook it up straight to my cable
line.

I'd make sure that the incoming signal is actually
good first.  This may be outside of your control,
depending on where the wires come into the
house/apartment.
