Common problem. You can use two baluns (75-300 ohm attached to 300-75 ohm) to isolate the cable. Better yet, call Comcast and inform them that the electrical code requires that the cable be grounded at the service entrance and have them come out and do the installation properly. If they hem and haw, tell them they have no choice. I suspect that there are millions of cable installations that are not to code and that Comcast doesn't want your city inspector doing an audit of their installations.
