A New Year and a New “Adventure”

[Nords]

Diffraction is our friend. With a nice high gain antenna, pointed at a ridge top, I'm confident the signal level on the other side of a ridge would be as high as, if not higher than what we could see from an omnidirectional antenna on a flat plain. 15 meters is a wavelength long enough to diffract fairly well over a 'rounded obstacle' like a ridge top.

I guess REWahoo would have to be equally concerned about the diffraction of the returning blast wavefront... analyzing those videos was the best part of the "Weapons Engineering" curriculum.
