Hey all!

I've had a stereo hum problem for some time and originally resolved it by buying a grounding filter for my cable line. The problem with the filter is that it severely reduces the picture quality and it kills digital signals.

I've tried various solutions with no success. My home theatre system is on its own circuit and I'm using a Panamax surge protection.

Anyway, the noise occurs when I plug in the cable line or antenna for my external antenna. They're both grounded outside, but I still get the ground loop.

One of the solutions I'm contemplating is connection a dual port ground block and grounding it to my panamax ground lug. I am under the impression that this will keep everything on the same ground. Am I smoking crack or does anyone thing this may help solve the problem. One of the reasons I'm holding off is that it'll be a bit of a process getting behind the system etc.

Here's a link to the grounding block: http://www.paladin-tools.com/view_tool.php?id=638&parent_id=316

So this I guess is my last resort. Right now I either have a really annoying audio hum or a crappy picture. I try to minimize the number of breaks in my cable and antenna runs.
