Buck,

I disagree with you on this. If the coil does indeed resonate the
antenna in 1/2 wave, antiresonance, current distribution will be
different than the straight quarterwave resonance. The current maximum
will occur in roughly the center of the loacing coil length with a
current minimum at the bottom. Since photon generation is an
ampere/length concern, there must be a greater peak coil current to
achieve the same power radiated. That would probably incur greater
losses than quarter wave resonance.

The half wave resonance might have an advantage if there is a problem
achieving an adequate counterpoise under the antenna for normal quarter
wave resonance. A lot of through-the-glass mobile antennas have been
sold using this principle.

I wonder if Roy has a simple way to include the coil Q or losses in the
EZNEC model. I'm sure there is a logical way to work it out but I
haven't had time to think it through yet.
