Can that system be extended to be in another part of the house?
For example, let's say there is a central DirecTV box supplying a TV in the kitchen upstairs and a TV in the basement. I would need a receiver in the basement and kitchen and a transmitter at the DirecTV box.
George, I just did a job similar to this. There were 5 DTV receivers in the mech. closet.
Since the HO didn't need control of other components, we ordered RF remotes from directv instead of using repeaters. They're working great so far. The remotes were about $25 each. The furthest one gets used from a receiver is about 30'. When I called directv, they were able to give me the distance limitations but I do not remember what they are. You can call their tech support and ask.
You can program multiple remotes to a single receiver. Each receiver has its own code that you program into the remote. Its very simple.
Lastly, make sure their receiver is capable of utilizing an RF remote control.
If you go into the settings menu, look for the 'remote' button, and if it has an option for IR or RF control, you're good to go. directv can assist w/ this also.
