More gain is RARELY "better". More gain is only needed when there are additional insertion losses in the distribution system that must be overcome.


Consider this scenario:

Location where all signals are weak to moderate.
50 of RG6 and a 2 port splitter, worst case insertion loss of around 7 dB.
Install a 15 db preamplifier and everything works.
Install a 30 dB preamp and everything still works.
The TV tuner's don't care about the extra signal power as long as it's not too much and that the amplifier hasn't introduced new distortion into the signal.
