It's not a Tailgater issue. That's the antenna and it can't connect to anything but the one single 211 series receiver. From the 211 receiver you need to run cables to each TV. If you want HD on more than one TV then you need to run multiple HDMI cables to each TV so a splitter and some running of new wiring will be required. If you only need HD on one TV but can get by with SD on the other TV(s) you can connect the main TV via HDMI and then run the receivers coax output to the coax video control center (or similar) to send that same channel to the other TV in SD.
