The unbound-state solution of the Schrödinger equation is examined for the potential that is defined as the sum of two δ'-functions of non-equal strengths. The analytical expression for the transmission coefficient is derived from the solution. The transmission coefficient has an absolute maximum at the zero wave number. Further, the transmission coefficient is shown to exhibit relative maxima and minima. Moreover, it is proved that the transmission coefficient in its relative maxima is larger and in its relative minima is smaller than the transmission coefficient for the corresponding single δ'-function potential.
