VSIS-EU Ground Loop Isolator

Ground Loop Isolator:  A Ground Isolator is used to eliminate the hum and horizontal bars caused by ground loops. When two or more devices are connected to a common ground through different paths, ground path noise or a ground loop can occur. This is actually quite common in home cable systems, even those that are well designed. The result of a ground loop is audio hum and/or horizontal bars in the TV picture.

If “beefing up" conventional ground connections and establishing solid ground points in your cable system does not resolve these problems, then a Ground Isolator is the most reliable way to fix it. The Ground Loop Isolator creates an electrical open on BOTH the center conductor and the outside shield, designed to work from 0-100Hz (DC current and AC current frequencies). The isolator allows cable signals above 100Hz to pass regardless of whether a ground differential exists between the two connection points.  It is virtually invisible to cable boxes and cable modems.
