I ran it through Spice ( laziness) - It doesn't resonate. Intuitively
you think it should have a low Q resonance at 1.6MHz , but it doesn't
Nice one.

finally come up The trick is to make
R = sqrt(L/C)
then the impedance is real everywhere. You can use any old values for L:
and C, as long as you make R=sqrt(L/C);
That equation is obviously know from transmission lines too..- Hide quoted text -

David,
After all those discussions where you have been baiting me on my
antenna
you finally come up with what I have been hitting you with.
Rember my comments where a radiator can be any shape, any elefation as
long as the
element is in equilibrium. Finally the penny has dropped with respect
to the LC ratio!
