Rev 1.0

Description:
Model SAF-1832731535-470-S1 is a K-band scalar
feed horn antenna that operates from 18 to 26.5
GHz. The antenna offers a 15 dBi nominal gain, 35
degree typical half power beamwidth. The nominal
sidelobe levels are -25 dB or lower. The scalar feedhorn is equipped with a 0.470” diameter circular
waveguide with UG-595/U compatible flange that
supports both linear and circular polarized
waveforms. A rectangular waveguide port configuration that only supports linear polarization isavailable under a different model number.
