If you are splitting a good cable feed a high quality passive splitter
should be fine.  You can get one for an acceptable price you at home depot.
One splitter with the correct number of outputs is much better then several
splitters daisy chained together.  Put terminators for any unused cable
jacks in your house.

If your cable feed to excessively weak you will have to use an amplifier.  I
split my cable signal six ways with passive splitters with no quality
