It's too bad he didn't do a controlled experiment, one system with the
tree and one without the tree. He gave a clue as to the performance.
He says it works much better after he added a 30 dB gain preamp. Did
you ever have to add a preamp to a 160 antenna?
Notice that it is one of the standard recipes for a "feedline common
mode current antenna", a balanced very low impedance load (that would be
the coil) driven directly by coax.
