Review on 🔌 TII 220 Ground Loop Isolator: Optimal Solution for Cable TV Applications by John Bennett

I have expensive home theater gear and recently added an Outlaw 5000x power amp to boost my Klipsch Reference Premier speakers. I noticed that as soon as I turned on the amp, a hum/static distortion came through the speakers. I checked the owner's manual and it said to check the cable line. Well after removing the cable line from the wall plate (where the cable goes straight out) the problem was gone. Realizing, yes, that it was a wire line, I noticed that Comcast hadn't properly grounded their wiring outside. Instead of telling Comcast that their technicians couldn't fix the problem, and to avoid arguments and headaches, I knew I had a ground loop fault that was causing this problem. I looked online and in the owner's manual and there were suggestions to install a ground loop. Insulator. As soon as it arrived I installed it into the wall plate, plugged everything back in and the hum/noise was gone. It's amazing that an $18 part can fix something even the cable company can't. Overkill today, everything works fine. Also, I have a voltage regulator that does nothing to eliminate noise/static. For those who buy it, as there are no instructions, look carefully at the part when fitting it. The "service" end of the product attaches to your wall plate (where the service is coming from) or to the coaxial line where your service is coming from. The "client" side connects to the coax cable that goes to your cable box/floor distributor (if you run cables to the modem and cable box).
