Broke TV jack of off TV, anyway to hook up amteanna to it bypassing the jack

There used be a short coax inside the old CRT TVs. With flat screen, I bet the coax fitting is soldered to a board, which you probably broke also.
Your only option would be to buy a stand alone HD tuner and feed HDMI to the (now) monitor.
