the first low-power microwave vacuum tubes had been developed using new principles; the Barkhausen–Kurz tube and the split-anode magnetron. These could...

(600-MHz) receiver and 0.5-W transmitter were built, both using Barkhausen–Kurz tubes. With the antennas placed flat on the ground some distance apart...
