Think of a half wave dipole -- you need good insulators on the end
of the half wave because the voltage there is very high, and the
current is very low. Uzing (pardon the pun) Z=E/I=High/Low yields
a high impedance.

This is a pretty simplified explanation, but if you think about
it it will work.

Hope it helps you to understand things a bit.

I have a much better understanding of how it all works now. I had an
idea that is how it would work but just couldn't visualize it. Been 27
years since electronics school and the old brain has gotten a little
fuzzy since then! 8-)

Thanks everyone for all your help!
