Abstract
Abstract The coupler arrangement has an input, a main line output and a tap output. A ferromagnetic coil has a first and second axial bore. A first winding passes through the first bore and has one end connected to the input and a second end connected to the main line output. A second winding has a first terminal connected to the input, passes through the second bore and has a second terminal connected to ground. A third winding has a first end portion connected to the tap output, passes through the second bore and has a second end portion connected to ground through a terminating resistor. A fourth winding has a first end portion connected to the tap output, passes through the first bore and has a second end portion connected to ground potential. The first and fourth windings are wound through the bore and around the outside portion of the core in a first direction, while the third and second winding are wound in the opposite direction. The first and third windings have a number of turns which is much smaller than the number of turns of the second and fourth winding.
