the ground loop is actually caused by voltage on the shield (ground) side of the coaxial cable. the noise actually shows the ground is not properly made at the entrance of the cable into your home. have the cable company come back (for free) because they did not properly install the cable. they may have installed a copper grounding wire to the entrance block but either it is not screwed down tightly at one end or both, or the wire's gauge is too small for the distance it is going to the ground, or perhaps it is not attached to a real ground at all. no matter what the problem is, the noise indicates there is voltage on the house side of the ground. the voltage may not be a danger to you now, but it does indicate that no matter what you've done to eliminate it with a transformer, or a any other method, the cable is still not properly installed and all you've done is cover up a problem, not repair it.
