It is fascinating stuff about the phasing of two wire bi-directional 
Beverages.  The idea of sending back the return signal on a single two 
wire Beverage to the same receiver via a phasing device is something I 
will try with the MFJ-1029 on my 900 foot WD-1A reversible.  I guess 
based on the pictorial that this would provide some null improvement but 
with multiple antennas spaced at the proper distance "at a fraction of a 
wave length" (whatever that is) you would expect come forward signal 
improvement.

I enjoy making these tests on the upper portion of the BC band and when 
visitors come in the shack show them how signals from some islands to 
the south east can appear with very clear copy and with the push of a 
button a station in P.R. takes over and the south east stations totally 
vanishes.  No carrier or any sign of the other.

Thanks for this paper from 1926 and remember few if an hams in the 50's 
and 60's on top band had any interest in constructing a Beverage.  The 
all of a sudden the Beverage rebirth took place to the point that if you 
have the space, a resistor and a roll of wire made you king in the RX 
department.
