A theoretical and experimental investigation was made of the factors affecting the performance of toroidal inductors with ferrite cores and windings of coaxial cable. Design procedures are developed and described for toroidal cable chokes which provide a specified minimum amount of rf isolation over a band of frequencies. It is shown how one may maximize the width of the frequency band for a given rf isolation impedance. The entire band, from 2 to 30 Mc, may be covered by a set of only three individual cable chokes, providing an rf isolation of better than 5,000 ohms.
