Abstract:
1. A ground loop isolator for a coaxial cable comprising: a first threaded element configured to couple with a first coaxial cable interface wherein said first threaded element surrounds a first electrical conductor; a second threaded element configured to couple with a second coaxial cable interface wherein said second threaded element surrounds a second electrical conductor; a ground loop isolator circuit coupled on one side with said first electrical conductor situated within said first threaded element and on an opposing side with said second electrical conductor situated within said second threaded element; said ground loop isolator circuit configured to a first shield configured to cover said one side of said ground loop isolator circuit and said first electrical conductor; a second shield configured to cover said opposing side of said ground loop isolator circuit and said second electrical conductor; said first shield and said second shield configured to reside a positive distance away from one another to form a gap and configured to shield said ground loop isolator circuit from external radio frequency electrical signals and further configured to prevent direct current from passing between said first shield and said second shield as a result of said gap; and, wherein said ground loop isolator circuit comprises a transformer having a first and second insulated coil wound about said transformer wherein said first insulated coil is coupled with said first electrical conductor forming a first electrical path on said one side that is grounded, and wherein said second insulated coil is coupled with said second electrical conductor forming a second electrical path on said opposing side that continues onto a floating voltage point that is not grounded, such that said first electrical path and said second electrical path are insulated from one another; and, wherein said first electrical path that is grounded is not connected to said second electrical path that is not grounded.
