Abstract
A radio frequency choke for a cable or CATV system is designed for blocking signals from 5 to 1000 MHz and passing 60 Hz AC power. The RF choke has a wire coil that is wound upon a coil form of a predetermined cross section, the coil being formed of a number of successive spaced windings on the form, with each winding being joined to the next by an air coil of at least one turn, formed off the loop. The various successive windings should have different numbers of turns. Forming the air coils tends to tighten the windings onto the form, so that a fixative coating or adhesive can be eliminated or omitted.
