SAC-1055-141-S2

Rev 1.1

Description:
Model SAC-1055-141-S2 is a V-band conical horn antennathat operates from 58 to 68 GHz. The antenna offers 10.4
dBi nominal gain and a typical half power beamwidth of 49
degrees on the E-Plane and 60 degrees on the H-Plane. The
horn also offers typical sidelobes of -30 dB on the E-Planeand -15 dB on the H-Plane. The conical horn antenna can
support linear and circular polarization. The input of this antenna is a 0.141” diameter circular
waveguide with UG-385/U flange.
