In most cases the Sky 60 can efficiently handle 4 TV's however some customers have had success with 6 or more. One thing that you may want to keep in mind is that more TV's you add the more likely that you'll need to invest in an amplified splitter to help boost the signal. You can find these devices on Amazon.com or at your local Best Buy, Wal-Mart, etc. They can cost from $10 - $60+ depending on which you choose.
