3-Way Cable Splitter

[Cubswin]

I purchased a 3-way cable splitter. It has two 8 dB outputs and one 4 dB output. I plan to hook my cable phone, computer router and pc tv tuner card to the 3 outputs. Which one should go into the 4 dB? Does it even make a difference?

TIA for the help!

I would probably call the cable company and find out. Signal strength for the phone might be the least required, whilst the TV and the 'net would require the most.
