Descripción The Resnatron was a high power UHF oscillating tetrode where electrodes, cathode, grids and anode, were integral part of the two cathode and anode resonating cavities, 3/4 or 1/2 wavelength long. In the early types, intended as UHF oscillators for radar jamming equipment during WWII, a small coupling loop between the two cavities provided the necessary feedback to make the resnatron to oscillate.
The Resnatron operated around 10 to 16KV anode voltage at about 100KW total power, generating up to 70KW RF output around 500MHz, with efficiency of up to 70%. The tubes operated continuously connected to a vacuum pump. A typical system required ten 10-ton trucks with two tubes in service and two more tubes kept continuously evacuated in stand-by.
In the ‘50s Westinghouse also built prototypes of amplifying Resnatrons, to be used in UHF television transmitters.
