For your situation connect a 3 way splitter for the distribution of the north north/west stations.

And if you choose to receive the south Tv stations then it will be a separate 3 way splitter and cabling to the 3 TV's and there will be remote control A/B switch at each Tv for selecting the north north/west stations or south stations.

If your friend has 4 Tv's then it's the same thing only use 4 way splitters. I suggest receive the north north/west Tv stations only , that way no double the wiring. .

To make a radar map of the exact location of your house go to the tvfool home page and go to the >>Start MAPS<< part of tvfool , move the pointer to your house location , make the antenna height 25 feet and make a radar map.
