SAF-1442241535-067-S1

AdvancedDescription:
Model SAF-1442241535-067-S1 is a G-band scalar feedhorn antenna that operates from 140 to 220 GHz. The
antenna offers a 15 dBi nominal gain, 35 degree typicalhalf power beamwidth, and -25 dB typical side lobelevel. The scalar feed horn is equipped with a 0.067”
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.
