Loop Admiration Society members, and friends:
You may like to consider a totally capacitor matching network as shown on
my website.
I suggest the transformer approach because when the loop conductor will have
some leakage current to the trees (it's small Mal <G>) 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.
