Evaluation of the VHF Band of a 140-600 MC Experimental Radio Direction Finder Developed by FTR Under NDRC Contract OEMsr-961

Abstract

This report covers the evaluation of the general electrical performance of the low frequency (140 to 300 megacycles) band of an experimental radio direction finder (total frequency range from 140 to 600 megacycles) developed by the Federal Telephone and this work was to determine the fundamentals of performance, particularly that of the collector system, and to obtain data for comparison with other types of direction finders in this frequency range. The results as given in this report bear out the fact that simple Adcock-goniometer type systems are unsatisfactory in this frequency range. The electrical characteristics of the receiver are satisfactory for an experimental equipment.
