As the water in the soil dissolves the salts conductivitity will increase, bit once (almost) everything is dissolved more water will make the solution "thinner" and thus decrease conductivity. Could it be that in places with a "natural" low soil loss (so most salt already dissolved) rain will increase the loss while with poor soil it will decrease ? By the way, an antenna in the middle of a sweet water lake might not work very well as sweet water is a rather poor conductor, in contradiction to salt water. Another thing I observed : during rainfall the loss resistance increases and only starts sinking a few hours (or even days) after the rain stops : day 1 (dry) : 115 Ohm day 2-3 (heavy rain) : gradual increase to 130 Ohm day 4-5 (dry) : gradual decrease to 95 Ohm day 6-10 (dry) : gradual increase to 115 Ohm I believe that the first increase is caused by the wet greenery, after the greenery dries up (but soil is still wet) the decrease starts and after the soil dries up I am back to start. 73, Rik ON7YD |
