The experimental ferrite loading of log conical antennas in a recessed cavity, and a free-standing log conical and helical antenna, reduced the size of the loaded antenna by at least one-half. The corresponding efficiencies of the ferrite-loaded antennas were approximately 25 percent of the unloaded antenna efficiencies. Temperature measurements of permeability show greatly increased losses above 200C. A preliminary study of a helix with ferrite loading is described. Author
