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.
