A passive 3-way splitter will attenuate 4 to 8 dB. Hopefully the manufacturer labeled the ports. (Often on three way splitters, one of the three outputs will have less loss)
You need much more attenuation. I suspect the strong signals are overloading the receiver front-end, which appears as signal break-ups.
Though it is counter-intuitive, a directional antenna is often needed for it's ability to reject multipath. If you get to the point where you try a directional antenna, you will most certainly need to attenuate the signal from it also.
But first, let's work with the antenna you have.
