The CV120 is an echelon strapped version of the CV41. It was used in the GL3 radar.

Heater voltage6V
Heater current7A
Max anode dissipation1kW
Wavelength10.70cm ±0.2
Typical operating conditions
Peak anode voltage *23kV
Peak anode current *40A
Average output peak power *360kW
Magnetic field *1350 oersteds
