SAR-2507-03-S2

WR-03 Pyramindal Horn Antenna, 25 dBi Gain
SAR-2507-03-S2 is a WR-03 pyramidal horn antenna that operates from
220 GHz to 330 GHz. The antenna offers 25 dBi nominal gain and atypical half power beamwidth of 9 degrees on the E-plane and 10
degrees on the H-plane. The antenna supports linear polarized
waveforms. The input of this antenna is a WR-03 waveguide with UG387/U-M Anti-Cocking flange.
