CATV Groundloop, toBeat a Dead Horse and the Shack

Sorry, I know this one has been discussed at great length (over and over) but I went down to pick up one of those Radio Shack ground loop interuptors only to discover that it's RCA only. Personally, having spent too much time and money on the interconnects within the system, I'd hate to now throw in Shack technology between components. Ideally, I'd like to put the interruptor on the coaxial line coming in, before it even hit the first component. Do we have the technology for such a feat? (Ok, I'm sure we do, but what's the best way to go about it)? Many thanks.

If you decide not to try the DIY approach, and want to pursue my earlier suggestion about the Mondial "MAGIC" unit, you can buy this unit from Audio Advisor. They also sell a nearly identical unit made by Tributaries, which is also priced at $99.

I bought a Modial Magic unit and it didn't work. Still have hum but only when the cable connection is attached to the stereo/video system. Friend who is an electric engineer couldn't get ride of it so ended up going to DirectTV. Problem went away. AT&T broadband is the culpret.

Keis,

I have DirectTV and still got hum from the cable (from the sat dish) connected to my system. A simple wire grounding the sheath (outside connector)of the cable works perfectly.

I just noticed a very affordable new (to me) coaxial isolation transformer device in the MCM Electronics preferred customer catalog. This one has type-F male at one end & female at the other. Stock #33-6925 list $17.19, presently selling for $12.95.
