Abstract:
A signal transmission system comprising:a) a power source for generating a power signals said power source including a signal conductor simultaneously carrying said power signal and a transmission signal; andb) a power takeoff inductor including:i) a coiled conductor longitudinally extending from a first end to a second end and defining a winding, one of said first and second conductor ends connected to said signal conductor for drawing said power signal off of said signal conductor; andii) a core longitudinally extending from a first end to a second end, said core disposed axially within said winding, said core first end adjacent said conductor first end and said core second end adjacent said conductor second end, said core comprising at least three individual core components having different magnetic permeability, each of which has a longitudinal hole, the core components being serially aligned to each other and longitudinally disposed from said core first end to said core second end, which forms a longitudinal hole from the core first end to the core second end;said coiled conductor receiving said power signal from said signal conductor without substantially degrading said transmission signal, andsaid inductor including a plurality of dielectric spacers between said at least three individual core components, each of the two immediately adjacent core components having at least one of the dielectric spacers therebetween.
