FIG. 6 shows the measured feed point impedance as a function of frequency of a very high frequency antenna constructed according to the embodiment of the invention depicted in FIG. 3.
FIG. 7 shows the measured voltage standing wave ratio as a function of frequency measured in the vicinity of the primary resonance frequency of a high frequency antenna constructed according to the embodiment of the invention depicted in FIG. 2.

The Corum bros wrote the following in 2008, caduceus toroid antennas: http://www.tuks.nl/pdf/Reference_Material/Corum/Toroidal%20helix%20antenna.pdf

George Hathaway had brief funding to work on toroid antenna experiments in 2011 (I don't know if this is paywalled PDF:) https://www.researchgate.net/publication/251709920_Electromagnetic_Radiation_Experiments_with_Transmitting_Contra-Wound_Toroidal_Coils

Also the infamous "missing" Corum rotary-fields paper from the 1994 proceedings of Tesla Symposium is found here: https://1lib.us/book/3499511/84d6bd?regionChanged=&redirect=236683546
