O.K., Cecil, I want to make a Fresnel lens antenna for forty meters.
What does it look like, and how do I make one?

Dunno, but the Fresnel Equation for the amplitude reflection coefficient,
assuming normal incidence, is the reflected electric field divided by
the incident electric field. Reckon your great, great, great, great,
great, great, great, great grandfather knew that along with Fresnel?

Hi Cecil,

Stumbling through optics again without a flashlight?

It would look like a beam. [Gad Tom, that was too easy.]
