I forgot the power/distance equation because I AM NOT AT WORK now. It is in 3dB drops at a certain frequency using the attenuation coeff. and attenuation coeff. of the atmosphere. Also the density of the atmosphere is an exponential function from top down. And only certain bands of RF can pass through the atmosphere without exciting H2O, O2, N2, etc. with any use.

If anyone wants to write the equation out, go for it.

What happens at work stays at work.

I'm no expert, but the EMP from a nuke detonated at altitude is composed of three components (E1,E2,E3). The EMP is the result of interaction between gamma rays and the earth's atmosphere. Also, EMP interacts with the ionosphere. The result is damage to everything within line-of-sight of the detonation.

A blast at 300 kilometers would have a line-of-sight footprint of???
