Abstract
Improvements in a directional derivative circuit, comprising two current transformers whose secondaries are connected at a point in the circuit from which it is defined in two opposite branches one of them terminated at a point where the circuit derives a signal in the ranges of frequency of vhf and uhf, that circulates by a third branch of the circuit, characterized essentially by the fact of intercalating in the other branch a circuit corrector of phase formed by a capacity and an inductance with losses, having the secondary of one of the transformers a number of turns slightly lower than the primary of the other transformer, with all of which remains, between the two intensities that, in the classical circuit, circulate with opposite directions in the branch terminated at the point where the signal is derived with attenuation of the same, a lag close to 180º, with which in the uhf range the high directionality that is obtained is maintained ne in vhf.
