AIRDUX

Illumitronic Engineering has developed a complete, versatile, series of air core inductors designed especially for the amateur rig, or for prototypes of RF transmission equipment. These coils may be used for pi output circuits, conventional LC output circuits, interstage and oscillator circuits. The series consists a standard coil type, a variable pitch type, and an indented type, available in a range of diameters from 1/2 inch to 3 inches.
