Also, our Winnebago has one of these to transfer HDMI from the compartment over the driver (where the box lives) to the living area TV. HDMI does not carry much more than 12 feet so for longer runs you need these. The Winnebago also has an infrared "repeater" that has a lens by the TV that "sees" the remote signal and transfers it to an emitter in the compartment where the sat box lives (the 211z does not have the RF remote the Wallys do). To watch different shows on different TVs using satellite, you do need 2 satellite boxes. I do not know if you can split an HDMI signal like cable TV and the small boxes I have seen only have 1 HDMI port. In any event, getting satellite to a bedroom TV is a real challenge as you either have to use a device like this (and find a way to run the wire) or find a way to get a direct run of coax between the box and the dish (to put the box by the TV).
