Wet ground is lossy, ice is an insulator, antenna current is mainly determined by Rloss ?? If you measure the unloaded antenna with a bridge, you will measure values for C and Rtotal. Rtotal include Rrad and Rloss. Rrad is very smal for amateur size amtennas and doesnt change much. So the Ground loss must be reduced.

Hi all
How can one explain that ant current rises when soil is frozen?

Conductivity of water should be much higher than that of ice.

So earth resistance would be higher and the current should drop when soil is frozen...
