Of current interest: Antenna range uses model techniques for radiation pattern measurements

The National Bureau of Standards (NBS) recently completed a new model antenna range to facilitate the measurement of antenna radiation patterns in the vertical plane. It is composed of an inverted V-type structure which supports a test or target transmitter more than 50 feet above a ground plane, in the center of which is placed the model antenna to be tested. The model techniques employed in this type of installation are being applied to an NBS investigation of the behavior of high-frequency antenna systems used in ionosphere-sounding equipment.
