  • Abstract
    The paper discusses methods of combining the signal currents from the different antennas in a directional receiving system and a detailed description is given of a system by which all phase and amplitude adjustments are performed upon the beating current inputs of a double detection receiver. The theoretically derived shape of the directional characteristic of a two-loop system has been verified by experiments, and data on reduction of static for such a system are given.
