Yo Jay,
Try to determine the path that your cable takes (from where it enters the house to the outlet that you connect your TV to) look for the possibility that it travels with AC power lines. Mine enters the house next to the meter and comes up through the same holes as the romex that runs to the receptacles.
This usually indicates that the electrician used the lazy-man's way of running the cable...he ran it thru existing holes that were drilled for the romex.
If your house has this, then the next call is to the cable company to have them run a new line from their splitter to your TV set.
Save your money on CATV isolaters and call Cox.
