Topband: Effect of trees

[Guy Olinger K2AV]

In general, without knowing any details, it could simply be an indication
of insufficient radials with a large seasonal change in ground moisture.
 If however during the dry season there is no change after a heavy rain and
the change remains constant across the season, then the smart betting is on
the trees.

Distance from wire to trunk(s) and distance to foliage would be useful.

73, Guy.
