Don't know how yours is wired, but on mine it was very easy. The park cable/sat coax input (only had one coax input) came into a two connector wall plate in a cabinet just below the living room TV, with a short coax jumper cable between the two connectors. From there it went to the amplifier/switch box in the bedroom. From the amp/switch box it went to both the bedroom and living room TVs.
I just removed the short jumper coax, connected a new longer coax cable from the incoming coax connector on the plate to the 211k, a new coax cable from the 211k coax output to the other connector on the plate (sending the signal to the bedroom), and connected an HDMI cable from the 211k to the living room TV.
That gives me the sat program on both TVs when the amp is switched off. With the amp switched on I could get OTA programs on either or both TVs.
Later I added a second incoming coax connector specifically for the sat input so I don't have to move the jumper to get park cable.
