Abstract:

This report covers the work done thus far in investigating a satisfactory solution for the medium frequency, polarization error free, shore navigational direction finder problem. There is described the fixed Adcock direction finder which was designed, installed and studied for this purpose. Following this, mathematical analyses and criteria are given for the degree of stability and balance required for good bearings in such a system. Quantitative analyses of the effects of unbalance and the simple method utilized for measuring small variations of antenna impedance unbalance with great accuracy as given herein may be used in conjunction with a suggested method for determining the suitability of fixed Adcock direction finder sites and ground networks,
