SAF-2234431535-328-S1

Rev 1.0

Description:
Model SAF-2234431535-328-S1 is a Ka-bandscalar feed horn antenna that operates from 22
to 44 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 is equipped with a Ø 0.328”
circular waveguide with UG-599/U compatible
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.
