[QUOTE="Terryl, post: 1073699, member: 369937"] The cable, HDTV sets or SAT boxes are isolated from the incoming AC mains service by a transformer in the power supply, this to protect the customer. Depending on the type of box, most of the time there is only a two prong plug for the AC mains, hot and neutral, no ground, if there were a ground then the RF modules coax connection would be isolated from chassis ground or AC service ground, this to prevent a possible ground loop problem.
