Here's an annoying add for sending a wireless signal to a second TV. I have no idea how well it works but it may be an option.
Myself, I'd just run another co-ax cable to the second TV. Also be aware that if you change the 9242 to dual tuner mode so you can watch separate programming on the second TV, you may lose some functions such as recording HD while watching a second HD program, or so I understand.
