The maximal value of radiation energy condition is determined experimentally for the power summation device of four identical magnetrons in the general resonator. The maximal radiation efficiency of the device by means calorimetric method with due regard of energy loss owing to thermal radiations, process of a heat transfer and free convection is determined which makes ~ 94 %.
