SAF-2434031535-358-X1

Rev. 1.0

Description:
Model SAF-2434031535-358-X1 is a Ka-band scalar feed hornantenna that operates from 24 to 42 GHz. The antenna offers a15 dBi nominal gain, 35 degree typical half power beamwidth.
The nominal side lobe levels are -25 dB or lower. The scalar feedhorn is equipped with a 0.358” diameter circular waveguidewith UG-599/U flange that supports both linear and circularpolarized waveforms. A rectangular waveguide port
configuration that only supports linear polarization is available under a different model number.
