Problem with hum from Directv coaxial cable

[MUDSHARK]

I'm getting persistent hum on my loudspeakers. I traced the problem to the coaxial satellite cable (directv). I can't find a rf isolator that will work on a satellite system. Something to do with the required DC in the cable that would be blocked by the isolator. Anyone had this problem? Any help would be appreciated.

Resolved?

Hi,
It's been awhile since you posted this.
Have you solved the problem? I think I have the same problem.
Any input would be welcome, thanks.

Both of you. Where does that satellite cable go to in the system that interacts with the audio system?
