Zusammenfassung:The report contains results of some flight tests performed on the Newburyport Antenna, a 3500 foot, multiplicative, scanning array operating at 30-50 mcs and providing multiple receiving beams one-half degree wide in azimuth. Calibration and testing procedures are described, with particular reference to patterns taken by focusing in the near field. Test results were encouraging but not conclusive, and emphasize the existence of major difficulties in the assessment of characteristics of directive antennas at frequencies below UHF. (Author)
