What’s the maximum number of TV’s that ZvBox can serve?

The Zv channel is a true HDTV channel, so it’s got the same “reach” as any other HDTV channel. If your current system has six TVs that receive HDTV channels, ZvBox will serve those same six TVs. In systems with many TVs and great lengths of cabling to traverse, a “line amplifier” is often used to strengthen the signal, and the Zv channel will work in that set-up as well, but must be properly installed.
