Rev. 1.1

Description:
Model SAF-5836831725-141-S1 is a V-band scalar feedhorn antenna that operates from 58 to 68 GHz. The
antenna offers a 17 dBi nominal gain, 25 degree typicalhalf power beamwidth, and -28.5 dB typical sidelobe
level. The scalar feed horn is equipped with a 0.141”
diameter circular waveguide that supports both linear
and circular polarization. A rectangular waveguide port configuration that only supports linear
polarization is available under a different model number.
