What is interesting is the system they use for counterpoise.

I have not had experience with this particular system but it is similar to
what is on my roof. I have a vertical antenna 26 feet high and it has a
radial system made of old 300 ohm TV Twin lead. There are big coils on the
antenna so it does not need much of an antenna tuner. It works from 4 to 30
MHz. To be more precise, it works on the ham bands from 10 to 80 meters, it
is not a broadband antenna.
The point is, such an antenna is reasonable and can work just fine. I talked
to Madagascar using this antenna from my home in Palo Alto, more than half
way around the world.
I have also used this antenna on the ground with a ground plane made of
chicken wire but now it is on the roof and my transmitter is on the second
floor. Ground is a fair ways away. It works either way. As I have said
before, connecting to ground is not a requirement for transmitting. You
will know if you have a bad ground because you will get a shock through the
microphone when you transmit. If your antenna is good and balanced, you will
have less of a problem.
These guys say they have worked out this antenna and that it works. I see
no reason to doubt them.
