Is the interference to you or to the TV signal? What is grounded and where? Perhaps you are causing a ground loop by doing grounding differently than they did or something?
If to the TV signal ? Are you using shielded cat5e cabling and grounding an end of the shield drain wire? Any other stuff installed with it, like mikrotiks or switches or anything? If to you, TV antennas on roofs don't transmit (currently). Any cell phone tower backhauls nearby or 5.8 phones? Perhaps the tv antennas are just a scapegoat.
