    A pre-amp will have a lower noise level than a distribution amp, and is therefore preferable.

    Without a meter or signal strength simulation tool (like TVFool), it is hard to know if amplifying the signal will cause the strongest signal to be too strong in your case, but I doubt you would have any problems. Anything more than 20dB would be overkill.

    You can always try just a splitter first, if you would like to see how it performs without any amplification.
