his antenna tuner, and his hearing before the signal arrives.
If the signal leaves the antenna before its transmitted, then the concern
over impedence matching would be for naught.


It would be great for getting in ahead of the pileups also.

how about building an antenna from this stuff:

it could suck energy from the receiver to power the transmitter.

And the ironic thing is that the velocity factor inside waveguide is
*always* greater than one. Really.

Hi Dave,

This was reported some time ago. One of the key properties is the
construction of a flat media that could focus light to an absolute
point instead of an area. I don't think they mention this at your
referenced page.

I've played with the models, but have still some way to go in this
segments intensive hog.

(WTF)
giving him the time to adjust his rotor,
his antenna tuner, and his hearing before the signal arrives.
If the signal leaves the antenna before its transmitted, then the concern
over impedance matching would be for naught. (LEAVES BEFORE TRANSMITTED
THAT IS A GOOD ONE)

how much for the dope, man?
