This is what the first radars looked like and there is a funny story with these antennas.
The Japanese spent two years hunting for a radar-equipped plane to investigate the mysterious antennas.
And when they finally got hold of the debris, it turned out that this antenna had been invented at the University of Tokyo by friends Odo and Yagi shortly before the war.
But since the principle "there is no prophet in his country" characterizes not only us, but all Asians in general, no one pays attention to their developments.
But the Americans took everything from the world.
