ALL RIGHT! thats the kind of assertion that should stir things up. I like
the 'slow-wave' part, thats a good one... maybe we should compare it to one
of those faster than light antennas in the patent archives and see if we can
get something going?

How about a loss of de-Corum...... ;^)

Sorry Cecil, I'm a sucker for a bad pun!

I'm not sure K1AON and KB1EUD would appreciate
your pun.

Funny thing is that I'm down with the slow-wave loading coil thing.
Maxwell's equations are your friend... not a very nice friend when
Bessel functions are involved, but...

Faster than light, though? Maybe the phase velocity in some tricky
cryogenic world, but I dunno...

Haven't seen much on superconducting antennas here... I read a paper
once with a superconducting magloop but they forgot to make the
matching network superconducting too.

Let's get the "bizarre but REAL" antenna thread going.

Wouldn't you like to have a QRP CW rig with a 3" magloop for 20m on the
top? The thermos full of liquid nitrogen is kind of a pain to lug
around...

Anyone built a "genetically" designed ham antenna yet? Might be a good
way to go for the "I have 50 feet between two trees to put up an 80m
dipole" crowd.

Maybe we could develop a combined performance+aesthetics genetic
algorithm to design efficient shortened vertical dipoles that look like
nice pieces of modern art and have a nice low voltage section to run
the coax out... you run the electromagnetic algorithm, weed out the
weak designs, then you have your neighbor click the most attractive
five and throw the rest out, and repeat!

And light has now gone faster than light. Well, sort of. It did get
there before it left in this case.
