RF engineers are a dying breed as well.
Odd in this wireless society.
Art + Science + Math
Pretty much replaced by modeling software that can be used by literally anyone with even a basic understanding of wavelength, take-off angles, capacitance and resistance.
Heck, I downloaded antenna modeling software and learned how to use it in about an hour. Built a home-brew 17m (18mhz) antenna in another hour and made contacts around the world same day.
If anyone knows an rf engineer with shaped beam experience...ping me
