SAC-2012-188-S2

Rev 1.2

Description:
Model SAC-2012-188-S2 is a U-band conical horn antenna that
operates from 43 to 50 GHz. The antenna offers 20 dBi nominal
gain and a typical half power beamwidth of 16 degrees on the Eplane and 20 degrees on the H-plane. The horn also offers typicalsidelobes of -20 dB on the E-plane and -28 dB on the H-plane. The
conical horn can support linear and circular polarization. The
input of this antenna is a 0.188” diameter circular waveguidewith UG-383/U-M anti-cocking flange.
