Some time ago I attempted to make direct measurements of the HF conductivity of trees, at least for the trunk and limbs. I simply put a two rings, with nails to penetrate through the bark, around the

Yes I am no doubt in that group. So do good conductors in the near field re-radiate most of the coupled energy (eg a parasitic element) while poor conductors dissipate it as heat? I would think poor

so far the discussion has only treated the effect of trees in the immediate near field area... what about the effect of wood in the Fresnel zone? especially at low angles the ground reflected ray wil

  I am well aware that I may be flamed (again) for starting "something", but I found this article where the conductivity of sap wood and hard wood is measured. It seems if I read it correctly, that w

So when the Suns magnetic field reverses and the sap starts flowing in the opposite direction will that affect the conductivity any? Sent from my iPhone _________________ Topband Reflector
