Very solidly populated with trees at this location but I have reports from
others that experience increased loss with increased ground moisture having
no trees. This demands further investigation!
Besides it is worth if it is loop or Marconi antenna. For loop seems dry
soil should be good. For the Marconi dry soil should be bad. And for
both antennas it should be good if trees are dry.
What I have wrote in previous letter is for marconi.
But any way all of this is speculations only. It requres comprehensive
experimental investigation realy.
