SAY-8731045005-094-S1

Rev. 1.0

Description:
Model SAY-8731045005-094-S1 is a Cassegrain antenna thatoffers a nominal gain of 50 dBi and a half power beamwidth of 0.5
degrees typically across the frequency range of 87 to 100 GHz.
The main reflector is fabricated with fiber glass to offer a lightweight and rugged mechanical structure. The corrugated horn isused to provide the best feed efficiency and the most uniform
illumination. The input port is a 0.094” diameter circular
waveguide with a UG-387/U-M flange. The antenna can support
both linear and circular polarized waveforms and is designed andmanufactured for indoor applications. By adding a modetransition, SAGE Millimeter model SWT-10094-SB, the input port becomes a standard WR-10 waveguidethat can only support linear polarized waveforms.
