But okay, the thing worked. The authors concluded that what they had
was a tuned circuit on the end of some coax, and the coax radiated more
so than the antenna. This sounds almost like aa halfwave antenna with
it's tuned circuit.

The problem with the EH and CFA as has been pointed out many times is the
claim to provide Electromagnetic radiation through Poynting Vector Synthesis.
They produce the E and H field seperately and combine the two in the antenna to
produce EM radiation. The claim is with this Synthesis, high radiation
efficiency is produced from a very small antenna, the Holy Grail, a small
efficient antenna.
If someone gets results from one of these antennas, it is due to feedline
radiation, so they will proclaim "it works". But it does not work because of
Poynting Vector Synthesis as claimed. There are a number of ways to get your
feedline to radiate, the EH antenna could be one of the better ones, along with
the commercial Bilal Isotron.
