Hi, Mal and Group.

Dick has indicated that Earth Resistance gets higher when the ground is
wet. That seems strange and contrary to accepted theory.
Realy he had mesure earth resistance plus enviroment loss resistance.
Also leak in isolators also yelds a loss. Enviroment loss can became
grater when dielectric enviroment (say dry wood) is wet. And wet
isolators in antenna wire sure yelds losses in oposite to the case when
they are dry.
Wet soil itself sure yelds decreasing of the losses. Say if it is not
a dielectric but a conductor (may be sometimes it is a good
dielectric (???) in very spesial case...).
