Apparently Cebik failed to do enough research thru 1920's literature.....why 
doesnt this surprise me.

The various magazines devoted to the consumer radio as well as the various 
radios instruction sheets include the counterpoise under the random length 
antenna. It was usually the option when a true ground connection was not 
available and its actual function was not fully understood yet except that 
it improved reception.

A magazine article followed by MFJ's Artificial Ground was another attempt 
of using a counterpoise to eliminate RF problems in the shack by resonating 
that wire without any thought of placement or polarity. I have no idea if it 
worked but Radiokit sold many of their parts kit version.
