SAF-2434231535-328-S1

Rev 1.1

Description:
Model SAF-2434231535-328-S1 is a Ka-bandscalar feed horn antenna that operates from24 to 42 GHz. The antenna offers a 15 dBi
nominal gain, 35 degree typical half power
beamwidth. The nominal side lobe levels are-25 dB or lower. The scalar feed horn isequipped with a 0.328” diameter circular
waveguide with UG-599/U compatible flangethat supports both linear and circularpolarized waveforms. A rectangular waveguide port configuration that only supports linear polarization
is available under a different model number. A dual-polarized configuration with an integrated
orthomode transducer is available under the model SAF-2434231535-328-S1-280-DP .
