VLF Ferrite Loop /&  other Loop / Antenna improvement.


United States Patent US3665476  - EXPIRED

This expired patent has some very insightful theory on loop antennas.  The patent its self would seem to do wonders for a receive system if it indeed works..  Maybe some one can try it? It sure sounds interesting.
