Rick (the Japanese one :-) ),

The diagram in the Japanese paper shows exactly my "earth antenna&quo= t; configuration. However I cannot read Japanese. Is it possible to give= a brief summary of the conclusions (in English)?

I will try to put this into a language package to see if I can obtain a Go= ogle translation.
