SAC-1532-04-S2

Rev 1.2

Description:
Model SAC-1532-04-S2 is a conical horn antenna with a WR04 rectangular waveguide interface that operates from 170
to 260 GHz. The antenna offers 15 dBi nominal gain and atypical half power beamwidth of 32 degrees on both the Eplane and H-plane. The horn also offers typical sidelobes of-15 dB on the E-plane and -20 dB on the H-plane. The conicalhorn can support linear polarization. The RF connector of this antenna is a WR-04 waveguide with UG387/U-M anti-cocking flange.
