I recommend you put in a new quality RG-6 line for the Tailgater.. here is why.
If you have one TV odds are you have a wall plate somewhere with a switch,, an LED indicator, an antenna connection and a more or less useless 12 volt outlet.
The cable you cite goes to the back of this thing.
YOu have to pull the wall plate, disconnect the cable and run it to the VIP- then run the cable from the VIP back to this port.
OR... You can run the front connector from the wall plate to the OTA jack on the VIP, (Assumign it has one, and I think it does). Then run a brand new RG-6 to the LNB jack, and run both Coax (59 or 6) to the TV as well as HDMI.
VIP off should pass park cable or OTA (Depending on the switch on the wall plate) VIP on Satellite.
