hes hilariously uninformed and talking out of his ass through most of this video. i like how he calls kreosans video fake (not that its not) and his proof is a comparison of the effects of a microwave gun on a tiny low powered battery powered device, to a mains voltage actual stereo system pulling a hell of a lot more power out the wall while being blasted by the microwave gun. or his claim that "you cant pull 2kw out of any outlet in your home" when you can pull about 2.2kw off the average house outlet.

Every family needs at least one Dayton somewhere on the family tree to make life interesting. Then there's always something cool going on down in the lab, and the opportunity to learn how & why things actually work. Plus, the math behind the physics fine tunes the engineering to get the actual desired results. When I was a teenager, I was so fascinated by high school physics that I constructed a cloud chamber with dry ice to look at atomic particles emitted by my dad's radium dial painted watch. But my niece's boyfriend recently built a cloud chamber that is cooled by an array of Peltier crystals - much, much better! Technology is always evolving and it's great to hang out with people who want to understand it all by experimenting with whatever comes to hand. So, here's a toast to Dayton and the spirit of experimental science & engineering. And thanks for sharing dude!

Sup Faud, I dug around in my e-mag knowledge a bit. Helical antennas create circularly polarized waves, which means that you would need a circular waveguide also. Waveguides only direct the wave, not create it. The antenna itself is on the magnetron - the piece just above the ceramic insulator. You would need to tap off of that to attach a different antenna. Beware, helical antennas' field lines go all over the place. To answer you directly: Yeah, it's possible, just... different.

If modified properly, this can make things glow white and poof into nothing in a matter of milliseconds. It's just that in order for it to be a long rage weapon, the lobes need to be focused to a sharp flux, and to be a practical weapon, would need a device within to adjust and focus the flux, and need to be rigged to a range finder through a computer, so that it automatically adjusts the flux. To make a basic microwave gun with decent range, maybe instead of that square horn mussle, stick the magnatron antennas into aluminum lined funnels, and over both of those, one larger aluminum lined funnel faced so that the small end is the end of the barell. Would that compress the lobes?

@BlueprintScience

The magnetron is tuned for a certain voltage so that the magnetron cavity can catch electrons at their "critical angle" - of course this has a lot of variation. If you could supply more current to the magnetron at the same voltage, it would be more powerful but it would heat up quickly. And magnetons suck at heat dissipation as it is.

Do the waves emitted, the figure 8, propagate all the way around the antenna? If you were looking horizontally at the antenna you would see a figure 8, but if you were looking directly at the antenna would you see a circle? I'm asking because it would appear your microwave is only using 1/4 of the wave emission @12:09.

So there are two main things of interest for every antenna, the near and far field patterns - the figure 8. Actually, it geometrically looks like a donut (name of shape is torus) around the stub antenna. It’s not a hard cutoff: it goes out forever. It only depicts where the most energy is. Also, yes, the microwave is not directing 100% of its energy into the oven. I’m actually not sure why. It could be a manufacturing constraint.

I was in microwave communications in the Marine Corps. Our waveguide was hooked to an 8ft parabolic dish. It transmitted in the direction the dish was pointed and the signal from the other location used the dish to focus the waves to the receiver in the center of the dish (about a foot or so away from the dish.) We transmitted line of site with about 10 watts. Our instructor told us that he was transmitting over a calm lake and they had 5x5 com over several miles on 1 watt. It took a bit more power for a troposcatter set up. This was 30 years ago. I don't even know if they use microwave communication any more.
