SAR-1430-42-S2-D

Rev. 1.3

Description:
Model SAR-1430-42-S2-D is a K-band pyramidal hornantenna that operates from 18 GHz to 26.5 GHz. Theantenna offers 14 dBi nominal gain and 33 degrees half
power beamwidth. The antenna supports linear
polarized waveforms. The input of this antenna is a WR42 waveguide with UG-595/U flange. The antenna isdesigned and manufactured for low cost applications by using die-case method.
