This quad ridged horn is a versatile antenna that can be used for a variety of purposes, including spherical near-field (SNF) testing and far-field range illumination. With its wide frequency bandwidth, it can replace several standard Open-Ended Waveguide (OEWG) probes or horns, eliminating the need to manually change range antennas. Quad ridged horns are typically smaller than equivalent OEWG probes at low frequencies, making near-field testing easier and more convenient.


  • Frequency range 5.0–50.0 GHz far-field use
  • Frequency range 5.0–26.5 GHz spherical near-field use
  • Wide bandwidth and low return loss
