Cylindrical Near-Field Scanner Systems

NSI-MI’s cylindrical scanners are well suited to testing fan beam, cellular base-station, stacked dipole arrays, and antennas that have broad azimuth and narrow elevation plane patterns. They are constructed to the highest standards and are based on years of experience. The scanner consists of two major components a probe tower and an azimuth positioner.
Small Cylindrical Near-Field Scanner Systems
0.9 m - 1.5 m (3'- 5')
The small cylindrical scanner systems are ideal for measuring broad beam (azimuth) antennas with apertures less than five feet making them ideal for testing stacked linear arrays.
Medium Cylindrical Near-Field Scanner Systems
1.8 m - 3.7 m (6'- 12')
The medium cylindrical scanner systems are ideal for measuring broad beam (azimuth) antennas with apertures less than twelve feet making them ideal for testing stacked linear arrays.
Large Cylindrical Near-Field Scanner Systems
5.5 m - 16.0 m (18'- 52')
The large cylindrical scanner systems are ideal for measuring broad beam (azimuth) antennas with apertures less than fifty two feet making them ideal for testing stacked linear arrays.
