Abstract
An RF choke for minimizing hum modulation in a coaxial cable system that carries broadband signals along with high amperage 60 Hz AC power signals. The choke contains two conductors wound about a rod core. The first conductor includes two groups of clockwise windings each containing three turns. The second conductor wound counterclockwise also contains two groups of winding one of which contains four turns and the other of which contains three turns. The two connectors are separated by a space of about 0.20″ and a 750 ohm resistor is placed in parallel over the second group of winding in the first conductor and a second 510 ohm resistor is placed in parallel over the first group of windings in the second conductor.
