Beverages depend on ground losses to function.
I respectfully beg to differ. The original Beverage was developed
to receive LF and VLF signals via groundwave. The lossy ground
caused the wave to "tilt" and hence it was able to induce a signal
into the horizontal Beverage wire. The situation on HF is different
as the ionosphere supplies the wave tilt in most cases. It might
actually be an advantage to make the antenna "deaf" to groundwave
signals in those cases where there is a strong local broadcast
station.
My understanding of the wire under the beverage was that it stabilizes
the impedance when the ground conductivity changes (after rain for
instance). A stable impedance makes for stable nulls.
