Abstract
Common mode noise can exist on an outer conductor of a female F-type port of a RF-device, like a cable modem box or cable TV set-top box. The present invention utilizes a jumper wire attached to an electrically conductive connector, having a shape and size to fit around a base of the F-type female coaxial port. The jumper wire carries the common mode noise away from the outer conductor of the port. In a first embodiment, the jumper wire is connected to a ground line of a household outlet. In a second embodiment, the jumper wire dissipates the noise signal by interacting with one or more ferrites. In a third embodiment, the jumper wire carries the noise signal to a shielding layer of a coaxial cable, which may further carry the noise signal to one or more ferrites or a ground connection.
