Content preview: 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.
