I suggest the transformer approach because when the loop conductor will have some leakage current to the trees (it's small Mal ) and this will be minimized if the loop is allowed to float relative to ground. My latest loop experiment is an octagonal TX loop with 3/4" X 10ft sides with a calculated Rac of .045 ohms for the conductor alone. Hope to be able to show that the ground loss tapers off to near 0 ohms when it's raised it to 50ft. If it doesn't fall off significantly, this may show the reflected radiated field absorption in addition to the magnetic field absorption is part of the Rac equation. Has anyone performed or know of an experiment like this at LF? If radiation reflection is at work here it may be possible to add a ground screen to improve matters.
