Even the invention of RADAR was originally inspired by an attempt to produce a suitable "death ray". Uninformed speculation, indeed. Yep. Garbage in. Dogma out. But, I'm sure once RADAR started being developed and improved, the military brains of the era thought/sought to weaponize it. Don't be so sure. The original idea in 1939 was to build a death ray that would cook the pilot of an attacking German airplane. The calculations were done and it was determined to be impossible. So, Watson-Watt asked "What can we do to help". Arnold Wilkins recalled that it was possible to detect an airplane when it created multipath interference patterns as the airplane flew between the transmitter and receiver. A field test was arranged, it worked, and the rest it history. https://en.wikipedia.org/wiki/History_of_radar "...had read about a German newspaper article claiming that the Germans had built a death ray using radio signals, accompanied by an image of a very large radio antenna." This video covers the early RADAR development quite nicely.

The -3dB width of an antenna pattern is called the "beam width".
