SAR-1725-15-S2

Rev 1.3

Description:
Model SAR-1725-15-S2 is a V-band pyramidal hornantenna that operates from 50 GHz to 75 GHz. Theantenna offers 15 dBi nominal gain and a typical half
power beamwidth of 26 degrees on the E-plane and 25
degrees on the H-plane. The antenna supports linear
polarized waveforms. The input of this antenna is a WR-15
waveguide with UG-385/U flange.
