We have found that some routers inject either an electric field or a radiofrequency signal into the shielding sheath of Cat7 cable, which then radiates into the room. This simple ground system shunts those fields to ground eliminating the unwanted broadcast from the cable and may even improve transmission quality. Easy to install, no tools required. Simply add the conductive tab to the Cat7 cable plug, then clip-on the ground cord. Depending on the chassis of your equipment, emissions from the connected computer and router may also decrease.
