I have a 722k in my living room using dual mode, and a solitary,(not combined with the sat. in cable), TV2 home distribution coax cable connected to a splitter going to a TV in the basement, and 2 TVs in my pole barn about 25' away.
I used to have the remote antenna in the barn and was able to change channels with the remote from there. I then had a Hopper/Joey installed and the tech. took that all apart. Now I've gone back to a 722k and I need to know how to combine the antenna and the home distribution connectors on the back of the receiver and what "devices" to use to combine the signals to go over the 1 coax wire going out to my barn where I will connect the antenna to another "device" and a splitter to connect to the 2 TVs I have in the barn. Can I also connect a remote antenna to a "device" in the cellar so I can also control the TV down there with a remote? By "devices" I mean splitters, combiners, seperators, duplexers etc. I've still got most, if not all of those devices from the initial install of the 722k, just don't know what to use.
