Input Transformers

The impedance of a large single turn loop antenna is very low. For optimum noise performance a step up input transformer is needed.

For this design the input transformers are wound on "L8" 25x15x10mm ferrite toroids. 12 turns input and 96 turns output for a 1:8 step up ratio. Properties of the L8 ferrite material are in this PDF
