In the diagram you are recommending a 3412 to replace the splitter that is connected directly to the antenna, correct? Then one output will go to the other splitter and one to the coax going to one of the 3 TV's.
Yes, but only if it is needed. It is a balancing act because of the great difference in strength between WSAW and W27AU. Too much amplification can cause tuner overload which might make it even more difficult to receive W27AU, because the distortion products from the overload might wipe out your weakest signals.

Code:
                                       TV 1 needing strongest signal
       outside                           /
Ant > grounding > coax > FM trap > CM3412            TV 2
       block                             \          /   
                                        2-Way Splitter 
                                                    \
                                                     TV 3
WSAW is your strongest signal with a Noise Margin of 78.6 dB, even before adding the antenna and amp gains, which puts it in the Overload category.
