Evaluation of Model CXFF Radio Direction Finder
Abstract
The Navy Model CXFF radio direction finder, developed by the Federal Telecommunications Laboratories of New York, under Bureau of Ships contract NXss-30834 was tested to determine the soundness of its operating principles and its suitability for Naval use. The equipment, covering the frequency range 140 - 600 Mc, employs four separate antenna arrays supported by and in front of square flat screens, arranged for mounting as a quadrangle around a ship's mast. The antenna outputs are alternately switched, by electronic means, to the input of a common receiver, the video output of which is synchronously switched through suitable amplifiers and a differentially connected variable resistive network, to a cathode ray tube.
