Re: NEC-LIST: HEMAC matching

Claus,

Do you mean helix rather than toroid? I imagine a helical coil wound around
a tree trunk, spiraling up, would give better coupling than a toroid. Have
you, or someone else, done this? The real issue is to set it up and get
some impedance data. Then one can do a matching network design. There is
no a priori good answer.

HEMAC = Hybrid electromagnetic antenna coupler

It is a coupling device allowing a tree to be used as an antenna. It is
a sort of toroidal air coil wound around the tree.
