I indeed measured the total resistance of the aerial system (minus the
coil loss) as I have explained in my e-mail. I agree with Mike that
"system loss" would have been a better _expression_ than
"earth resistance".

Indeed, but it usually done at 50Hz. To be meaningful at LF the
measurement should be performed at an LF frequency. But I'm afraid that
will not be so simple.
