I have a home that has numerous coaxial jacks throughout. They aren't be used for TV of any kind (cable or satellite). However, there are splitters on some of the lines. One line from outside feeds 2-3 rooms (depending on line) inside the house.
Could I possibly use a MoCA kit of some kind over these coaxial lines even though they have splitters on them?

Each time the signal goes forward through a 1 to 2 splitter the signal ends up less than half of its original strength. So the answer is maybe, and the speed will be reduced going one way.
