It will take a whole lot more signal degradation to reach the Weak
Force threshold (about 83dB more, just to compare to the Strong Force
- much less a standard dipole).

Hi Frank,

Your results will no doubt be shunned as unauthentic (in spite of his
program being NEC based, but 20+ years older - we won't go into his
confusion of not knowing what NEC is).

I've noticed an old hobby horse trotted out to the starting gate:

This nostrum was offered years ago to explain "efficiency," and no
doubt the corruption of what "efficiency" means will be used to muddy
the stupendous loss into figures of amazing merit.

It should come as no surprise that even allowing (patronizing the
authur as several contributors here desire) for this aberrant reading
of "efficiency" (per unit length) that the authur's Weak Force Antenna
design is not one ten-thousandth the size of the standard dipole. As
such, this new design is still not as "efficient per unit length" as a
standard dipole when the authur's terms are accepted.

Not sure what to say. I have designed some ultra compact vehicular
helices for 0.54 to 210 MHz. Network analyzer measurements
indicated the models as very close to that predicted by NEC2.

The project was abandoned due to very poor results -- even with
a 30 dB pre-amp the reception was unsatisfactory. The auto
manufacturers are desperate to have a vehicular BC/FM/Digital
antenna that fits into a "Sharkfin" shaped radome.

Heck, I may have to build one of Art's models and measure the
parameters.

You know Frank, there is always the possibility that what I have is in
fact a induction
heater without radiation shielding. In other words the copper actually
radiates a larger portion of energy into heat
if there is a ferro magnetic material with in the near field! So a
heat test is required on the antenna in a field where
there is no possibility of induction heating. Thinking out loud here
as I have not read up on the subject of induction heating
which I thought was a result of hysterysis of ferro magnetic materials
where I am using a diamagnetic material. There maybe a spill over of
sciences here
