Pick yourself up a coax ground-loop transformer
and install it on the main cable service before
it enters the distribution center.
One caveat: some transformers do not provide true isolation from input to output; i.e., there may be a D.C. connection. To be sure, use an ohmmeter to test between one 300 ohm terminal and the coax pin and then the shield, and then from the other 300 ohm terminal to the coax pin and shield. You're looking for no conductivity.
