SAF-2434231725-328-S1

Rev. 1.0

Description:
Model SAF-2434231725-328-S1 is a Ka-band scalar
feed horn antenna that covers several popular 5G
bands in the frequency range of 24 to 42 GHz. The
horn antenna offers a nominal gain of 17 dBi, typicalhalf power beamwidth of 25 degrees and side lobelevels of -25 dB or lower. The antenna port is a0.328” diameter circular waveguide with a UG599/U-M flange that supports both linear andcircular polarized waveforms. A rectangular waveguide port configuration that only supports linearpolarization is available under a different model number. The dual polarized configuration withorthomode transducer integrated is available under the model SAF-2434231725-328-S1-280-DP.
