SAF-2633031728-28-S1

Rev 1.1

Description:
Model SAF-2633031728-28-S1 is a Ka band scalar feed hornantenna that operates from 26 to 30 GHz. The antenna offers
17 dBi nominal gain, 28 degrees typical half power
beamwidth, and -25 dB typical side lobe levels. The scalar
feed horn is equipped with a WR-28 rectangular waveguidethat supports vertical linear polarization. Circular waveguideports supporting vertical and horizontal linear polarization, as well as left and right hand circularpolarization, are available under a different model number.
