ABSTRACT:
An RF Choke and tap having improved insertion loss, amplitude modulated distortion of video and audio carrier signals at CATV frequencies. The RF choke includes a 20 AWG magnetic wire wound on a ferrite rod. The magnetic field effects of the choke are optimized by selecting the choke winding pattern, rod core material and positioning of a resistor between selected windings. The wire is wound by placing two groups of the 4 tightly wound wires adjacent the ends of the rod. A group of 3 very loosely wound wires is separated from the wound wires and placed between the groups of 4 tightly wound wires. A resistor is electrically connected to a first wire in one of the groups of tightly wound wires and connected to a first wire in the group of the loosely wound wires.
