Wow, that sounds pretty cool. Imaging being able to do VLF work from an apartment. I wonder how easily it scales up in frequency. The big question is, what does it cost?

I am highly suspicious of the purported capabilities of this "antenna" , at best it is a Hi Q acoustical resonator. Any electro magnetic fields radiated from it are incidental to the fact that it is being excited with an electrical signal. I doubt that it would radiate exceptionally well. I see no practical advantage to conventional antennas.
