SAR-2507-42-S2 Rev. 1.
WR-42 Pyramidal Horn Antenna, 25 dBi Gain
SAGE Millimeter, Inc.
Description:
Model SAR-2507-42-S2 is a K-band pyramidal horn
antenna that operates from 18 GHz to 26.5 GHz. The
antenna offers 25 dBi nominal gain and a typical half
power beamwidth of 7 degrees on the E-plane and 9
degrees on the H-plane. The antenna supports linear
polarized waveforms. The input of this antenna is a
WR-42 waveguide with UG-595/U flange.
