As long as you are capturing enough signal to begin with. A 2 way splitter will send a little less than 1/2 the captured signal to each TV but with digital information this may not cause any problems, 1/2 the signal does not mean 1/2 the information.

I just happened to be using the 4-way splitter before I added the CM777 pre-amp.
I tried to give you a link but this site prevented it.
You know how to find me. LOL
