I sure enjoy the discussion on this topic. However, I would like to sheepishly, perhaps foolishly, ask if folding the short vertical Beverage termination down lead wire back and forth on itself with some small spacers would reduce the vertical pick up somewhat due to a cancellation effect.?

Another means, although more complex, might be to mount the termination resister at the high point and construction the earthing wire out of Tri-Ax forming a Faraday shield. The Faraday shield principles work well at AF and Video mitigating induced hum in long runs of cable. Maybe since the Beverage is totally unbalanced end to end these ideas just would not apply. Please let me know and I don't mind being flamed for my suggestion. It is all part of the learning process.

I disagree that the quantity of signal induced in this manner is not 
detrimental to
performance.  All you have to do is insert a short piece of wire into the
antenna jack of your receiver to know how much signal that short piece can
deliver.

I believe that small amount of signal from unwanted directions can, in


many


instances, totally obscure a weak signal from the desired direction.
