Small Cylindrical Near-Field Scanner Systems

0.9 m (3')
1.5 m (5') Cylindrical Near-field System


Small Cylindrical Near-field Measurement Systems are ideal for measuring broad beam (azimuth) antennas with apertures less than five feet making them ideal for testing stacked linear arrays. The scanners consist of a vertical probe tower with up to a 1.5 m (5’) travel, high capacity stepper motor based azimuth positioner, control computer, software and cabling. The high capacity probe carriage can accommodate probes as low as S-band including optional roll and translation stages. This simple design is easy to assemble and align, accurate, and can be dismantled for transport or storage within one working day.
