I have a garage that is fed with a 3 wire feed from one pole transformer and my house is same from a different pole transformer. Both locations have a ground rod attached to the box. The cable TV is connected to both sites using a splitter. ( This was installed by the cable company before I bought the house) Is this a possible ground problem? The cable eventually connects the shield to the ground of each television in both locations. Saw a similar post the other day that got me thinking.....
