In Reply to: Re: Will Monster Power Strip Solve Ground Loop Problem? posted by db on June 5, 2001 at 17:28:00:
I have noticed when bringing in an outside source, like DSS, or Analog Sat systems, and even cable, that their ground potential can be different from your power company's ground. This can create the hum. Trouble is, if you lift ground, you stand a better chance at getting zapped by lightning, because the cable is on a pole somewhere, same for the SAT, and DSS, on a roof or out in the yard. You could try to get a better ground by driving rods deep into the earth,(9 to 12 feet, interlocking brass rods, local RS) and connecting the cable ground there, instead of where the cable company grounded, minimal at best. It still might not remove the noise. Also, the cable may be sending the noise with their signal, at the headend, they use consumer SAT recievers, with -10db unbalanced outs, a bunch of noise originates there too, because it is boosted up to broadcast level for their modulators, without interfacing, thus raising the hum with it. Another thing to try, get the remote box away from the TV, and see if that helps.
